Jessica Simpson is a showstopper … and that was the case even when she was a teenager.

In a Twitter post labeled the "ultimate #tbt" (that's Throwback Thursday for you non-tweeters), the 32-year-old mom shared a five-minute video of herself in high school performing the lead role of Cassie in her alma mater's production of "A Chorus Line."

Long before Dita Von Teese was the raven-haired queen of burlesque, she was Heather Renee Sweet — a classic American bottle blonde with a sun-kissed glow.

Earlier this week, the performer tweeted a selection of pictures from her Rochester, Michigan, high school yearbook. In the snapshots, the teen beauty rocks big '80s hair and even bigger '80s fashions, which run the gamut from demure to daring.

Who is Ethan Hawke's most memorable on-screen kiss? The one and only Angelina Jolie! The 43-year-old actor stopped by "Watch What Happens Live" this week to promote his latest flick "Before Midnight" and wound up telling host Andy Cohen about his steamy smooch with the brunette bombshell in their 2004 film "Taking Lives."

"With all due respect, the woman has been in the press a lot lately, but the best on-screen kiss I ever had was Angelina Jolie," he admitted, adding, "Angelina Jolie was born to whittle men and to make them weak when she kisses you. You don't know your name."

Well, apparently their chemistry was so amazing that, at the time, the two were even heavily rumored to be continuing their romance in real life. But, of course, Angelina is now happily in a relationship with Brad Pitt while Ethan, who divorced Uma Thurman in 2004, is married to Ryan Shawhughes.

Oprah Winfrey goes to the Ivy League. (Paul Marotta/Getty Images)Oprah didn't give out any free cars, but she did offer some words of wisdom for nada on Thursday.

The Mississippi native and media mogul spoke to approximately 1,800 students and their families at the graduation ceremony of Harvard University in Cambridge, Massachusetts. She was also awarded with an honorary Doctor of Laws degree.

"Oh my goodness. I'm at HAAAARVARD"" she joked at the beginning of her speech, adding that she had not hidden prizes under the seats in the crowd, as she was once known for doing on her show.

Henry Cavill as Superman (Warner Bros)Channing Tatum as Magic Mike (Warner Bros) Channing Tatum and Henry Cavill made headlines this week with revelations about how they relate to their bodies – and it's not the stuff of smirking confidence you might find on a movie poster.

“I was fat … I was Fat Cavill," British actor Henry admitted to the summer issue of Details magazine.

One wouldn't expect that candor from a young man whose pumped shoulders are weighed with rebooting a Superman franchise.

Likewise for Tatum, the flexing stallion of "Magic Mike." His projected image tends to disrobe and save the day, but, admittedly, he'd rather skip the major sacrifice it takes to look the part.

"I'm a fat kid on the inside," he recently told Cosmo. "I love food so much and I fluctuate about 25 to 30 pounds between movies."

Tatum underscores his preference for pizza, cheeseburgers, and beer in the article. Cavill also forgoes the conventions of a leading man magazine profile – no cheeky breakdown of his diet and ab routine, but instead a palpable anxiety.

"They’d get me up at

Katie Couric went on Howard Stern’s SiriusXM radio show on Wednesday and dished about her Hollywood romances, and the men that “got away,” including Bob Saget and Jeff Probst! The 56-year-old talked about her date with “Full House” star Bob Saget, admitting, "I had fun, I don't think I did it for him." Clearly she didn’t, since he never called her back for a second date. Weird, Danny Tanner seemed like such a nice guy!

Thankfully, Couric didn’t let that failed romance stop her from trying to find love in showbiz. The former “Today” show anchor said she also went out with “Survivor” host Jeff Probst. It seems his attire was a little more than she could handle. "I think he had puka shells on -- that was kind of a weird thing,”she admitted. Katie told Howard that she wasn’t too upset that it didn’t work out with either of them, adding, "I can't say that I was devastated that neither called me back. I thought they were both nice guys ... I don't think there was real magic there with either, but I enjoyed spending time with them."

Bob and Jeff aren’t the only men in the biz who Katie has admitted dating. She revealed back in February on “Jimmy Kimmel Live!” that she embarked on a … much less than romantic … date with Larry King more than 20 years ago.

While things might not have worked out with any of these guys, the mother of two has managed to find long-term love again with NYC financier John Molner. The two have been an item since summer 2012.

One year into motherhood, Hilary Duff is starting to learn the ropes of parenting.

And it’s not all fun and games, especially when you live in Hollywood and have photographers trailing you and your child every time you step outside of the house.

"It's hard having a baby and having paparazzi follow you all around all the time," she explains in a new interview with "omg! Insider," airing Thursday.

Amanda Bynes (Splash News)Amanda Bynes has an answer to the question many have been speculating about.

"I'm Not Crazy," she wrote on Twitter on Wednesday. Just three little words, but words with a whole lot of meaning in light of recent events.
