After keeping close company with Olivia Wilde in May and then receiving an honor from Charlize Theron last week, The Hangover star is generating the most talk because of his dinner companion this weekend.
She was no other than the recently available Jennifer Lopez.
Although the Internet lit up with reports of a budding romance between Cooper, 37, and Lopez, 42, a source tells PEOPLE that the dinner Saturday at the New York restaurant Per Se was all business.
The pair, according to the source, are "in discussions regarding a project."
