"Big Bang Theory" star Johnny Galecki is a single man. The 39-year-old actor and Kelli Garner split after two years of dating, US Weekly reports.

The couple, who went public with their romance in March 2012, is still friendly despite the breakup.

"It's all good," a source told E! News. "They still hang out a lot."

Galecki is also close friends with another ex-girlfriend: his "Big Bang" costar Kaley Cuoco. According to E!, Galecki brought Garner to Cuoco's New Year's Eve wedding to Ryan Sweeting. Recently the actor and his costars - Cuoco and Jim Parsons - negotiated new deals for Season 8 of the hit CBS show. According to Deadline, they each stand to make $1 million per episode.

The contracts extend for the next three years and cover them up until Season 10. There is also a possibility for an 11th season. A source told Deadline that the new deals include signing bonuses, back-end advances and production deals.

"In addition to tripling their most recent salaries of $35,000 an episode... Parsons, Galecki and Cuoco also quadrupled their previous ownership of the show, which has gone up from 0.25 to more than a point," Deadline wrote. "Parson's pact includes a production deal that spans TV and features and possible theater."

The deals for Cuoco and Galecki also include "producing arrangements."

The trios costars Mayim Bialik and Melissa Rauch previously landed new deals which included significant raises. Simon Helburg and Kunal Nayyar also signed new contracts and will get a reported $70 million over the next three seasons.
