Scarlett Johansson vs. Alanis Morissette: Fight! No, it's not for Ryan Reynolds' affection (although Alanis was formerly engaged to ScarJo's current flame) -- they're releasing albums on the same day! Alanis' Flavors of Entanglement and Scarlett's Anywhere I Lay My Head both hit stores on May 20th.

It's 50 Cent vs. Kanye West all over again!
