Jennifer Lawrence and her boyfriend Nicholas Hoult have been dating on and off since 2011, and Nicholas Hoult recently opened up to Metro UK about keeping his relationship with Jennifer Lawrence private despite their fame.

"I always find it odd when people look into my personal life. I'm pretty private. The more people know about you and your personal life, or see you out and about, getting a photograph taken, the more difficult it is for them to imagine you playing a character," Jennifer Lawrence's boyfriend said.

"I don't want people to just associate my work with my personal life," Nicholas Hoult added.

Nicholas also said he makes sure he keeps things professional when working with Jennifer Lawrence on the set of "X-Men: Days Of Future Past."

"Any couple who work in the same environment don't behave like a couple when they're at work, and it's like that on set," he said.

Meanwhile, Jennifer Lawrence spent the 2013 holiday season with her boyfriend Nicholas Hoult and his family at their home in Hampshire, England. Now, Nicholas' younger sister Clarista tells British gossip magazine Heat about J.Law's visit, Cosmopolitan reports.

"Jen is lovely. She's really easy to talk to," Clarista said, referring to the "American Hustle" actress by her nickname.

"She's really family orientated, so she fitted in well with us. She doesn't seem like a Hollywood type, she just mucked in. We're a very unglam family. In our house if you want a drink, you get it yourself," she said, suggesting that the Hollywood actress was very down-to-earth with Hoult's family.

Cosmopolitan reports that Jennifer also helped Nicholas' father bake a chicken pie, and made some cakes too.

She and Hoult were spotted at the pub together in Hampshire over the holidays, when they stopped to take photos with fans.

Jennifer and Nicholas met on the set of "X-Men: First Class" in 2011. They split in January, 2013 after dating for two years, due to their busy schedules. But the two stars bonded again in June while filming "X-Men: Days of Future Past" in Montreal, Hollywood Life reports. They have been dating again since last summer.
