Jennifer Lawrence & Nicholas Hoult: Partying Pair at

Teaming up for the extravagent celebrations, Jennifer Lawrence and Nicholas Hoult attended the world premiere party in London together earlier this week.

While promoting her new film “The Hunger Games: Catching Fire,” the 23-year-old actress stepped out with her on-again-off-again boyfriend at the Royal Court of Justice.

A lucky fan managed to snap a photo of Jennifer chatting with another party-goer while Nicholas talked on his cellphone.

Not only was the “Warm Bodies” star at the premiere, but his sister Rosanna Hoult stopped by for the festivities as well.

“On route to the Hunger Games London premiere, Excited!” Rosanna tweeted.

Jennifer and Nicholas called off their relationship in January but was rumored to have rekindled their romance in August after promoting their upcoming film “X-Men: Days of Future Past” at the 2013 Comic-Con in San Diego, California.
