The New "Who's Who"

We already told you that Megan Fox is the new Angelina Jolie in the next Tomb Raider movie, but that begs the question: what other Hollywood shoes are being stepped into? Click through our gallery to see who we think is the hot new blood.

Lady GaGa looks like a hipster version of her dance pop predecessor, Gwen Stefani. They are both known for their signature flaxen hair and are big in fashion circles on account their Ziggy Stardust-influenced senses of style.

A big toothy smile, huge brown puppy dog eyes, and American Sweetheart status make Anne Hathaway the new Julia Roberts. Pretty Woman and Erin Brockovich were to Julia's career what The Devil Wears Prada and Rachel Getting Married are to Anne.

Now that Jessica Simpson is singing country music and showing off some serious curves, she's quickly becoming the new Dolly Parton. Both bubbly blondes have a sweet nature, a nice Southern drawl, and really big, um, voices.

Rihanna is the new Mary J. Blige. Since both singers seem to cameo on just about every album in existence, how amazing would it be if they joined forces, activated their wonder-bob powers, and did a song together? Beyonce's head would explode.

Now that the Gossip Girl craze has swept the nation like Sudoku, Blake Lively is the Carrie Bradshaw of teenagers. SJP has passed the Chanel-laden torch to uptown Manhattan's newest fashion icon.

Squeaky clean, loved by all, a spitting image of Dad and the star of the upcoming Karate Kid remake, Jaden is the new Will Smith. Almost literally. The lucrative leading man roles will be piling up… as soon as he's a man.
