The two stars acted like a couple at a party recently.
At a recent afterparty for the movie The Hangover Part II in New York, Bradley Cooper and Olivia Wilde flirted hard.
“They’re definitely hooking up,” a source said.
Last year, Wilde auditioned for the film Limitless featuring Cooper. The two stars recently resumed contact.
“Olivia acted jealous when other girls came up to him,” the source continued.
Two days earlier, the duo had left together from a Saturday Night Live afterparty.
Wilde has also dated Justin Timberlake, another recent conquest.
“She thought going with Bradley would make JT jealous,” added the insider.
However, the actress’ rep denies that they are forming a couple: “Olivia is single and not dating Bradley.”
Wilde has also been seen with Ryan Gosling.
“Guys have been coming after her since the moment she filed for divorce!”
