Academy Award winning actress Jennifer Lawrence is reportedly not fond of Kristen Stewart.

According to Star magazine, the Hunger Games star is not happy that her boyfriend, Nicholas Hoult will work with the 23-year-old actress in the upcoming sci-flick Equals.

"She doesn't trust her," a source close to Lawrence told the publication.

Last year in July, Stewart and British director Rupert Sanders, who worked together on Snow White And The Huntsman, were photographed kissing in the Hollywood hills. After the news broke out, Stewart, who was dating Robert Pattinson then, split, but were reunited recently. It was previously reported that Pattinson's family and friends are not happy with his reunion with Stewart.

"They can't stand Kristen; his family is terrified that he'll never get away from her," an insider told Life & Style magaizne. "They think she's bad news."

Pattinson's family means the world to him, "but there's something about Kristen that he just can't resist," the source added.

Meanwhile, Sander's wife, model/actress Liberty Ross, spoke in detail about the difficult phase she was going through, during an interview with Vanity Fair.

"It was horrible," she said, adding: "It was really the worst, really the worst."

"I have no words to describe what we went through," Ross said. "But I think, for me, something always has to completely die for there to be a rebirth. And, for me, I feel like I'm going through a rebirth."
