Bradley Cooper is said to be "overwhelmed" by "intense" Zoe Saldana and her demands to settle down.

The two have been secretly dating for the last couple of months after meeting on the set of their new movie. Eyewitnesses reportedly spied them kissing publicly at the Sundance Film Festival two weeks ago and they made no move to hide their romance.

However, despite not making an official outing as a couple, their relationship is said to be moving fast and Bradley is feeling as though he is being pushed into developing things.

"Zoe is really intense," an insider told In Touch Weekly. "She just came out of a long-term relationship with Keith Britton, and now she really wants to settle down."

Apparently, Zoe has decided that Bradley is "the one" but the feeling isn't mutual just yet. "Bradley really likes her, but he’s trying to keep things casual," the source added.
