Word on the street is that the reigning sexiest man alive Bradley Cooper and hot ‘Avatar’ actress Zoe Saldana “are totally dating” and they are now just beginning to tell family and friends according to a report by E! News.

Why not? The two are very much single. Cooper has been seen out and about with a few, and Saldana recently called off her engagement to long time love of 11 years Keith Britton.

The two recently met on the set of new film the ‘The Words,’ a thriller also starring Olivia Wilde, Dennis Quaid and Jeremy Irons, due out in 2012, where they apparently got to practice much kissing.

Of course, a month ago when they were seen together at a Manhattan nightclub, Saldana’s rep denied the two were an item but word is they are dating and are planning a ski trip in the Rockies over the holidays.
