Zoe Saldana "really wants to settle down" with Bradley Cooper, says a source.

The Hollywood pair have been dating for the last few months after first being introduced last February when production began on their film The Words.

Despite being instantly attracted to each other, the two apparently didn't officially get together until Zoe, 33, ended her long-term relationship with her partner of 11 years Keith Britton in November.

Now sources have claimed Zoe is keen to take her relationship with Bradley to the next level.

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

The insider added that Zoe believes Bradley is "The One" and wants more commitment from him. However, the Hollywood hunk apparently wants to keep the romance relaxed.

"Bradley really likes her, but he's trying to keep things casual," the source added.

Zoe and Bradley have previously been spotted showing their passion for one another while out and about. The pair spent December 31 together when they attended a 40s themed party in Los Angeles.

They surprised guests with their flirtatious manner.

"They were making out for 20 minutes!" a source laughed to Us Weekly at the time.
