Aww, why so shy?

Yesterday Jennifer Aniston was snapped after getting her hair done, and the former Friends star made every effort to hide as she made a beeline from the exit to her car. Sorry Jen, but that jacket isn't an invisibility cloak!

Maybe she's still bummed about ex-husband Brad Pitt's recent engagement to Angelina Jolie? Then again, maybe not! A source recently told Us Weekly, "She hates it being brought up because she doesn't really care."
