Academy Award winning actress Jennifer Lawrence is reportedly angry with Kristen Stewart after rumours emerged that she is dating her former boyfriend Nicholas Hoult.

Hoult and the 24-year-old Twilight actress were first spotted together enjoying a sushi meal at the Tsukiji Market in Tokyo, Japan on 31 July. Later, the two attended the Tokyo press conference to announce their upcoming sci-flick Equals.

"Jen thought Kristen was her buddy. Now she thinks Kristen stabbed her in the back and took her man," an insider told InTouch magazine.

The X-Men: Days of Future Past co-stars had split for the second time recently and blamed their difficult schedules for the break-up.

"Kristen got her hooks into Nicholas pretty quick. He's fallen hard for her. Kristen's more his type. She's independent and anti-Hollywood and laid-back just like he is. She's the opposite of Jennifer, who can be a bit manic," another source revealed.

"Jennifer feels like she's been played for a fool, and she's furious," the insider added. "[Kristen] sunk her fangs into her friend's boyfriend and didn't care who she hurt."

Last December a source told Star magazine that Lawrence is not fond of Stewart, especially after her affair with married British director Rupert Sanders was exposed.

However, during an interview with Marie Claire, the Hunger Games star said the article of her jealousy over Stewart was amusing.

She said: "There was something in a magazine, and I was like, 'Oh, my God, that's hilarious', because Kristen and I are friends. I actually texted her a picture of it and was like, 'Just so you know, this is absolutely true'."
