Jennifer Lawrence and Kristen Stewart are reportedly into a "Hunger Games & Twilight Feud," and the reason behind it? KStew is actually in a movie with JLaw's British ex-boyfriend Nicholas Hoult.

According to UsWeekly, the "X-Men Days of Future Past" stars have parted ways for the second time (first was in 2013).

"They just weren't together a lot, her life is a whirlwind.... It just got to be too hard for now," the alleged source revealed.

And the reason behind the breakup? Well according to E! News : "They spent a lot of time apart because of work and it was difficult on their relationship." Adding that it "was very amicable."

The reports came following Hoult and his "Equals" co-star Kristen Stewart sporting her new do were spotted dining in a sushi bar together in Tokyo.

A photo of the two was posted in Twitter by @turducken09 who was in the same sushi bar with them captioning it with:

"Had the best sushi breky this morning at Daiwa in Tsukiji Fish Market w/ famous peeps. #kristenstewart #nicholashoult (sic)."

It was previously reported by National Enquirer that Jennifer Lawrence and Kristen Stewart are in for a "Hunger Games and Twilight feud" and that JLaw is worried about KStew spending time with her boyfie Nicholas Hoult saying: "Considering Kristen's history with British men, she's the last person Jennifer wants to see kissing her boyfriend on the set."

The source of the publication added that "Hunger Games" star Jennifer Lawrence is "determined to make time to visit the Equals set and keep a watch over Nick."

However, those rumors were soon refuted by the Hunger Games Mockingjay star claiming that she and KStew had exchanged emails and had already cleared any alleged rift between them.

"I wrote her an email because there was this huge, like, article about a Twilight and Hunger Games feud. And we've never met before and never spoken," Hunger Games Mockingjay star Jennifer Lawrence told Access Hollywood.  "I just shot her an email, and was like, 'Hey, can't wait to see more as this feud unfolds!'"

"[Kristen] wrote me back, and she was like, 'It's fine. Welcome to [our] world where everything you say gets turned into [something it's not].'" She added, "So, she understood."
