Hannigan on Independence Day (Splash News)

Alyson Hannigan has been in nesting mode since the birth of her second daughter, Keeva, in May. But there was a big celebration in her neighborhood for Independence Day, so it was a family day out for the actress and her brood.

The "How I Met Your Mother" star was decked out in stars and stripes for a July 4^th block party near her Brentwood, California, home. It wasn't about what the 38-year-old was wearing though — it was about what she was pushing, which was a pink-and-black stroller with her infant daughter Keeva inside. At one point during the festivities, Hannigan took the 6-week-old baby out of the stroller and strapped her into a black-and-white carrier.

Add one more perk to the list that famous actors get. While the rest of the world has to arrange for day care and babysitters, or wrestle with the decision of whether a parent can afford to give up a career to stay home with the kids, celebs don't have to worry about the issue, since it seems bringing your kid to work is perfectly acceptable in Hollywood. (Lucky them!) We've recently spotted everyone from Angelina Jolie to Charlize Theron toting their tots on set, and yesterday, Tina Fey, 42, showed off 11-month-old daughter Penelope while she was in Princeton, New Jersey, shooting her latest flick, "Admission."

In the film, Fey stars as a college admissions counselor who has a boyfriend, played by Michael Sheen, but starts up a romantic relationship with a potential student, portrayed by Paul Rudd. The movie is not to be confused with "Admissions" (note the "s"), which also comes out next year. That film stars Vera Farmiga and Andy Garcia, and tells the story of a couple

Oh, what a difference a decade makes. Back in 2002, the "Good Will Hunting" star was a single guy, still out playing the field. Fast forward 10 years, and the now-41-year old has his hands full with being a father to four girls with wife Luciana Barroso, whom he married in December 2005. The couple took three-quarters of their brood for lunch at Italian restaurant Sor Tino in the L.A. enclave of Brentwood on Saturday. Matt held hands with 6-year-old Isabella and 3-year-old Gia, while mom carried the newest member of the family — Stella, who turns 2 this fall. The girls' eldest sister, 13-year-old Alexia, Luciana's daughter from a previous relationship, sat the excursion out.

Damon first met his wife at a bar in Miami, where she was working, and hasn't looked back since.

"I genuinely feel like something incredible happened the first time I saw her," he told Britain's The Independent in 2011, noting that since their meeting was love at first sight, he didn't hesitate to

Adele's next album could be filled with sweet lullabies! The British songstress shared the happy news that she and her boyfriend, Simon Konecki, are starting a family.

"I'm delighted to announce that Simon and I are expecting our first child together," the 24-year-old singer wrote on her official website on Friday. "I wanted you to hear the news direct from me. Obviously, we're over the moon and very excited, but please respect our privacy at this precious time."

It's been an exciting year for the singing sensation. In January, she won six Grammy Awards, including Album of the Year, for 21. It was the most Grammys ever won by a female artist in one night. Konecki, a 36-year-old former financier who co-founded the U.K. bottled water company Life Water, was by her side for the career milestone.

A month earlier, Adele took her blog to address rumors about her relationship with Konecki, which began last summer, following a tabloid report that he was married. "Contrary to

The singer and her husband, motocross racer Carey Hart, brought their 1-year-old to the beach in Malibu, California, on Wednesday. Dressed in a yellow cardigan and rolled up print pants, Willow played in the sand with a bright green bucket as her parents looked on. Pink, whose hair is back to its trademark color, had an animated conversation with her little girl when it was time to pack up.

The same day, Pink and Willow enjoyed a mother-daughter shopping spree at the Malibu store Toy Crazy, which specializes in educational toys. Inside the shop, Willow — who turned 1 on June 2 — appeared to be picking out some new playthings. Soon after, they emerged with Pink carrying her daughter as well as a large shopping bag.

The 32-year-old "Raise Your Glass" rocker announced earlier this year that she's working on her sixth studio album. The first track, "Blow Me (One Last Kiss)," will be released on July 9 — and Willow will be featured. "Willow played bells," Pink said in the

Jack Osbourne's new motto, "adapt and overcome," appears to be working! Despite his recent Multiple Sclerosis diagnosis, the son of Sharon and Ozzy is remaining upbeat and focusing on the positive, including his two-month-old daughter Pearl Clementine.

On Tuesday, Jack tweeted a photo of himself and his little water bug in a swimming pool. The adorable little girl had a white cap and pink sunglasses for her dip with dad. The 26-year-old, who revealed some of his many tattoos in the photo, beamed as he kept a firm grip on Pearl, whose mother is his fiancée, Lisa Stelly.

While this tiny glimpse into his life appears to be picture perfect, Jack — a TV producer — was given life-changing news just two weeks after Pearl was born in April. After suddenly losing eyesight in one eye, tests revealed that he is suffering from Multiple Sclerosis — the autoimmune disease that affects the central nervous system, often causing vision loss, paralysis, and cognitive damage.

The Jolie-Pitt twins are pretty brave kids. Knox and Vivienne, who will turn 4 next month, didn't seem to bat an eye as they watched their mother Angelina Jolie — decked out in a long cape, facial prostheses, and giant horns coming out of her head — film a scene for her upcoming flick "Maleficent" on Wednesday in Buckinghamshire, England. After watching from afar in a field with their nanny, Knox and Vivienne were able to get up close in between takes. Jolie, 37, was even spotted walking around in full costume with Knox on her hip.

"It's a really great script and I'm having a lot of fun," the actress said in March of the Disney movie, which will be a reimagining of "Sleeping Beauty" from the perspective of the villainess. "My kids are very happy." And so is Jolie. The iconic fairytale "is not anti-princess, but it's the first time they're looking at this epic woman [in a different way]," she explained. "I hope in the end you see a woman who is capable of being many things,

Howdy, Maxwell. (Twitter)

Jessica Simpson is clearly a proud mama. On Tuesday, the singer-turned-fashion mogul tweeted an adorable photo of her daughter Maxwell Drew, who was born on May 1. "Howdy friends," Simpson wrote in the caption, which accompanied the pic of her big-eyed (and big-lipped!) little girl in a red-and-white striped onesie. Just a few days before, the new mom tweeted a photo of her post-baby cleavage as she prepared to take a stroll around her neighborhood with the message: "Street legal?"

This new pic is the first time the public has seen Maxwell since she made her debut on the cover of People magazine on May 30. "Life has completely changed," Simpson, 31, told the magazine. "From how I sleep to what I think about, Maxwell has definitely taken over everything!" The new mom and her fiancé, former NFL player Eric Johnson, also revealed that their first child has inherited her famous mother's eyes and her daddy's calm demeanor. "We stare at her all the time," said Simpson of Maxwell,
