Jennifer Lawrence's boyfriend apparently finds her flirtatious behaviour "funny".

The Hunger Games star has been dating British actor Nicholas Hoult for around two years after the pair met on the set of X-Men: First Class.

Jennifer was recently spotted laughing and joking with musician John Mayer at Los Angeles themed restaurant Medieval Times.

Jennifer's beau apparently has a good sense of humour about her friendly ways.

"Nick thinks her flirting was funny," a pal of the actor told Us Weekly. "He trusts Jennifer. She gets hit on all the time because they are separated a lot, but they're still in love."

The publication claims that the 21-year-old actress and the bad boy musician seemed to get on very well together as they partied with a group of friends earlier this month.

"They were playful and nudging shoulders," a source revealed, adding that Jennifer "was the only one listening to him."

John apparently amused Jennifer by repeatedly ordering her more drinks throughout the evening.

"[John] kept telling the waitress to get her more beers as a joke implying that he wanted to get her drunk," another source said. "She laughed about it."

The 34-year-old lothario has dated some of the most beautiful women in Hollywood including Jennifer Aniston, Jessica Simpson and Taylor Swift.
