Jennifer Lawrence dating ex Nicholas Hault seems to be the buzz swirling the web at this gorgeous May day. Oscar-winner Jennifer Lawrence was seen having a romantic dinner with her ex Nicholas Hault Monday, sparking the blogosphere and entertainment press to speculate that the two are officially dating…again.

The “X Men Origins” co-stars met up at The Little Door restaurant in Hollywood, all the while trying to keep their meeting under wraps with no success. Their images together were taken by paparazzi as they left through a rear exit.

According to a source, “"They arrived together. It looked like a date.” The source, however, added that the two weren’t overly affectionate. There have also been rumors that the Silver Lining actress is dating co-star Bradley Cooper.

Jennifer Lawrence, 22, and Nicholas Hault, 23, reportedly split in January after dating for two years. At the same time, an insider told In Touch that the couple are “young and grew apart, but they remain friends.”

Last year, Jennifer told Elle, "[My boyfriend] is honestly my best friend, and hopefully I'm his best friend too. He's my favorite person to be around and he makes me laugh harder than anybody."

Both stars’ fame and careers have skyrocketed recently. Jennifer landed the coveted role of Katniss in the “Hunger Games” series and won an Oscar for “Silver Linings Playbook” this year. Nicholas starred in “Warm Bodies” and “Jack The Giant Slayer.” The two stars will be back together next year in the new “X Men” installment “Days of Future Past.”

Jennifer Lawrence and Nicholas Hault met on the set of “X Men” in 2010.
