Jennifer Lawrence 'Jealous' of Kristen Stewart Working with Ex-Boyfriend Nicholas Hoult

Academy Award winning actress Jennifer Lawrence is reportedly not happy about Kristen Stewart working with her former boyfriend Nicholas Hoult.

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.

Just after the couple's break-up news broke out, rumours emerged that Hoult and the 24-year-old Twilight actress are dating, as the two were 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.

"Nick and Jennifer haven't been able to spend much time together recently as they've both been so busy. Jennifer isn't normally the jealous type, but she was wary of Kristen and felt jealous that she was working with Nicholas," a source told Closer magazine.

"Nicholas and Jennifer are great together - he swears nothing is going on with Kristen, and friends hope he and Jen can make it work," an insider added.

In 2012, Stewart went through a high-profile breakup herself.

Stewart and British director Rupert Sanders, who worked together on Snow White And The Huntsman, were photographed kissing in the Hollywood hills.

Following that, Robert Pattinson ended his four-year relationship with Stewart.

In an interview with Esquire UK, the 28-year-old actor opened up about the cheating scandal.

"Shit happens, you know? It's just young people... it's normal! And honestly, who gives a shit?" he said.

"The hardest part was talking about it afterwards. Because when you talk about other people, it affects them in ways you can't predict," Pattinson added.
