hollywood Jessica Alba birthday music box theatre lauren sanchez beanie

Jessica and hubby Cash Warren (who are both looking might fine these days) didn't bat an eye when we asked them about Cash's rumored hook-up with Lindsay Lohan while leaving a birthday party Friday night.

The happy couple braved the rain to celebrate Extra reporter Lauren Sanchez' b-day bash at the Music Box theater.

Earlier in the day, Jessica shot a commercial for Revlon, where she tweeted,"only took 2.5 hrs to get 'natural' look." Not as if she needed it!
