Cameron Diaz secretly dating Bradley Cooper

Showbiz Spy has reason to believe that Cameron Diaz is dating 'The Holiday' actor Bradley Cooper on the quiet.

The pair were spotted at an American Football match on Sunday, and later, looked intimate at Morgan's Hotel.

A source commented: "[They] were very close and lovely. Something is definitely going on, and it's clear they are more than just friends."

Sources also say the two have been sending each other "flirty" text messages for the past couple of weeks. Flirty text messages? Amateurs. Get on the clam and do it like it should be done.

Cooper, who has recently divorced, was romantically connected with Jennifer Aniston last month.
