Awkward Celebrity PDA

Jennifer Aniston & John Mayer

Rumour has it that Jennifer Aniston's inconstant romance with John Mayer was already on life support when they stepped out at the 2009 Academy Awards, where she presented in front of a crowd that included Brad Pitt and Angelina Jolie. Not surprisingly, soon after Jen squirmed and made this please-stop-touching-me face in John's embrace at a post-Oscars bash, they once again pulled the plug on their relationship.
