Jennifer Lawrence is less "stressed out" dating Darren Aronofsky

A source told People magazine: "She struggled when she dated Chris [Martin] and seemed very stressed out. With Darren, it will probably be different.

"He does not attract attention like Chris does. He is very low-key. He does not seem like a person who enjoys being a celebrity. Jennifer is the same."

Meanwhile, the pair have been spotted enjoying a number of low-key dates in Los Angeles recently.

A source said: "Jennifer and Darren have tried to keep things low-key and under wraps but they are really into each other.

"Recently Jennifer was working on a gruelling project and she relied on Darren for support and they were in constant contact. It seemed to show they were the real deal."

And Jennifer recently revealed what she looks for in a man - someone who goes out of their way to "impress" her.

She said: "It's not a sad thing to be alone. I think what I was trying to get across was that I don't feel a lack of something not being in a relationship. I don't feel like there is a hole to be filled ... An emotional hole to be filled ... You know, I'm 25. I'm successful. But I'm a girl. So I'm still always going to be attracted to somebody who impresses me."
