John Mayer, Jennifer Aniston, and her high heels hit the town on Sunday night, spotted ducking out of Villa in Hollywood. By Monday morning, John was out running errands — and picking up a few things at Fred Segal, fun — around LA showing off his fuzzy buzz cut. While John stocked up on some new goodies, Jennifer flexed her more charitable arm. She signed on to participate in the Sept. 5 Stand Up to Cancer telethon alongside other celebrities like America Ferrera, Casey Affleck, Lance Armstrong, Christina Applegate, and more. Sounds like the combination of funny and sweet is just what makes this hot couple click.
