It would seem, outwardly, that there is no bad blood between megastar Jennifer Lawrence and her ex-boyfriend, NIcholas Hoult.

As reported by E! News, the couple, who co-starred in the new X-Men films "X-Men: First Class" and "X-Men: Days of Future Past," broke up for the second time this past Friday. The couple had previously split more than a year ago, but decided to rekindle their relationship last summer, in 2013.

E! News's sources divulged some new info about just why the couple split up. Apparently, the split was "very amicable," but "they spent a lot of time apart because of work, and it was difficult on their relationship."

As well, Lawrence had previously spoken to Marie Claire about her relationship with Hoult, and how low-key the two "X-Men" stars were playing their romance.

"When we're busy, we agree to mutually ignore each other. Not completely, but neither of us gets mad when the other doesn't text back or call. Life's super-busy. Obviously you know what they're doing, and you trust them. We're so young that it would almost be like if we lived in the same city, what would happen? We'd be living together. At least this way he's in the same boat as I am: We can go out and have our own lives and know that we have each other."

However, things might not be as amicable as they seem, according to a new piece in KpopStarz. Their sources indicate that Lawrence has begun feuding with Kristen Stewart over Hoult, given that Hoult and Stewart were recently seen together in a sushi bar, and may have begun dating.

KpopStarz also reports that Stewart and Hoult will be starring together in the film "Equals," which may cause even more bad blood between the two of them and Jennifer Lawrence.

While this may be nothing more than Hollywood gossip, it could also be the start of a nasty "Twilight" vs. "Hunger Games" war. Check back soon for more details on Stewart and Lawrence's potential feud.
