A few months back Jessica Alba cropped her hair into a bob. Then she grew it out. At the time, we thought maybe she didn't like it or couldn't be bothered with the upkeep, but now she's gone short again, and she obviously likes it because this time she took to Twitter to show off her new cut, which got its debut at an afternoon tea with Revlon and beauty eds. Both Alexa Chung and Lara Bingle have recently shown off new bobs, so it looks like it's officially the haircut de jour. Do you like Jessica's new angular style? Not so much? It's very Gwyneth Paltrow, isn't it?
