JENNIFER LAWRENCE  hun­gers to shack up with hunky British BF, but her mother has ix-nayed it.

Now the super-talented thesp, 21,  – who plays heroine Katniss Everdeen in the smash hit “Hunger Games” – is worried about losing beau Nicholas Hoult, 22, insiders say.

“Jennifer is crazy about Nicholas!” a source told The ENQUIRER.

“They ’r e antsy to move into her Los An­geles home together, but her mother Karen is very much against it. She thinks they’re both too young and need to focus on their careers instead of complicating their lives with domestic matters.”

Last year, Jennifer was nominated for an Oscar for her performance as a backwoods teen in “Winter’s Bone,” which led to her role in “Hunger Games.”

Jennifer met Nicholas in 2010 when they co-starred in “X-Men: First Class” and the love­birds began dating shortly after filming ended.

While Nicholas is begging Jen­nifer to ignore her mother and put their romance first, she’s thinking twice about their plans to live to­gether, according to the source.

“Jennifer has a lot of respect for her mother, so she’s really torn about living with Nicholas,” said the source.

“The bottom line is she’s ex­tremely confused and trying to find a compromise to please both her mom and her boyfriend.”
