John Mayer was "all over" a mystery woman at the weekend, it has been claimed.

The musician, who is rumored to be dating Jennifer Aniston, reportedly canoodled with a beautiful blonde stranger while partying with Maroon 5 frontman Adam Levine in a New York club on Friday night.

Jennifer Love Hewitt and Patrick Dempsey are the Sexiest Woman and Man on TV.

The 'Ghost Whisperer' beauty and 'Grey's Anatomy' actor each grace different covers of TV Guide magazine's Sexiest Stars issue, and Dempsey said the honor was "very flattering".
