How You Know Her: This actress' career was born and bred by Nickelodeon with roles on The Adventures of Pete and Pete and Clarissa Explains it All, and the title role in the movie Harriet the Spy. She has moved up through the primetime TV ranks with roles on Buffy the Vampire Slayer, House, and Gossip Girl, but you can catch her back on the big screen in the upcoming turn-back-the-clock comedy, 17 Again. Going from child actor to budding starlet, we salute Michelle's shorts for boldly doing what not many Nick kids have done before: Being relevant past the teen years.

Whats Your Vue?

Say It's Not So Mandy!

Only one month after confirming her engagement, Mandy Moore has gone bridal, marrying indie rocker Ryan Adams.

The pair, who've dated on and off for the past year, tied the knot in a small ceremony on Tuesday in Savannah, Ga., the actress-singer's publicist confirms to E! News.

While Moore, 24, had weddings with Shane West and John Krasinski in A Walk to Remember and License to Wed, respectively, this is the first real-life marriage for both her and Adams, 34.

Significant Hottie:Katherine Heigl

While her fate is up in the air on Grey's Anatomy, Katherine Heigl will keep plenty busy even if her tenure at Seattle Grace comes to a tragic end.

She will join Ashton Kutcher in the Lionsgate thriller Five Killers, which, depending on how her Seattle Grace storyline plays out, will either be her Grey's hiatus movie or her first post-op project.

Killers will see Heigl playing a woman who marries her very own McDreamy while on vacation, only to find her newlywed life threatened after learning the couple next door are assassins out to kill her and her hubby. The film reunites Heigl with Robert Luketic, who directed her in the upcoming rom-com The Ugly Truth.

Cameras roll next month in Atlanta and the south of France.
