Jennifer Lawrence was reportedly upset to see her ex-boyfriend Nicholas Hoult by Kristen Stewart's side while she recently took the Ice Bucket Challenge.

A lot is being said about how Jennifer Lawrence is not very happy with her ex-boyfriend Nicholas Hoult hanging out with Kristen Stewart. Though similar rumors that made the rounds in the past were rubbished, the latest update is that Lawrence is furious with Hoult and Stewart yet again.

Recently, Stewart took the Ice Bucket Challenge, and it was Nicholas Hoult (and not Robert Pattinson) who was by her side. If you haven't heard of the Ice Bucket Challenge by now, then you must be living under a rock. The effort, created to raise funds for ALS research, has taken the celebrity world by storm.

According to the latest print of OK! Magazine, Lawrence was upset seeing the video because she was of the opinion that Hoult and she were just on a break and hadn't totally split.

"It's been only a few weeks since Jennifer Lawrence broke it off with Nicholas Hoult, but Kristen moves fast! Kristen, who stars as Nicholas's lover in their upcoming film Equals is making her move...K-Stew is sweet on Nick. This is so low-class from Jennifer's point of view. As far as she's concerned, she and Nicholas are just on a break," the tabloid reported.

Stewart and Hoult are currently in Tokyo, Japan, to co-star as lovers in "Equals", and rumors of them being more than just friends or co-stars emerged after photographs of them on a dinner date went viral. Although it is normal for two co-stars to go out for dinner, the date comes just a few days after a rumored split between Hoult and Lawrence made the rounds.

Reportedly, Lawrence's "explosive ego" caused a rift in their relationship, and since then the actor has been spotted getting cozy with other actresses, including Riley Keough.

"Jen is still desperately trying to get back with Nicholas after he broke up with her," a Celebrity Fix source revealed. "They're still talking but Nicholas is moving on. He hates how in love with fame Jen is, and he told her he hates dating an A-list actress."

This is not the first time a controversy revolving around the two leading ladies has made the rounds. In May 2012, Hollywood Life reported that Stewart and Lawrence were battling it out to bag a role in the film "Lie Down in Darkness." This professional battle later led to a personal feud, which of course the actresses denied. In fact, they were so bent on proving that there was no rivalry and that they planned a "girls night out" and hung out together at the Toronto Film Festival in September that year. The two were even seen embracing each other at the red carpet during the Academy Awards

"She's so cool," Stewart said of the Hunger Games actress, according to MTV News. "I was a lot younger than her when I first sort of entered this world of franchise land, and I don't know, I guess we sort of both went, 'Wow, this is so weird.' We actually sat in a corner with Emma Watson as well, the three of us. We were like, 'Wow, this is strange. This is really cool.'"

It is reported that the 23-year-old Lawrence even attempted to clear all the rumors and bad-blood fueled by the media between the two through an email in 2012, reports entertainmentwise.com. Co-incidentally the two represent rival French brands, Dior and Chanel. Lawrence is the face of Dior handbags, which also has Robert Pattinson fronting the fragrance Dior Homme!
