They say it’s never smart to mix business with pleasure, but it seems that Jennifer Lawrence doesn’t abide by that rule.

At last night’s annual SAG Awards, the “Winter’s Bone” star showed up on the arm of her “X-Men: First Class” costar, Nicholast Hoult.

Of the new duo, a source told Us magazine, “They walked in arm and arm and were lovey-dovey.”

Lawrence - who was a SAG Award nominee for “Winter’s Bone” - and Hoult were spotted together both at the show and the Weinstien Company’s after party at the Sunset Towers in West Hollywood.
