Good friends are hard to find – so you can’t let romance rumors ruin your relationship.

Kaley Cuoco and Johnny Galecki spent a fun night out together at the launch party for the video game Fallout 4 in downtown Los Angeles on Thursday night. The actors have starred together on The Big Bang Theory since 2007 and play a married couple onscreen.

Cuoco, 29, wore a white tank top, black shorts and a black-and-white, color-block jacket draped over her shoulders. She arrived at the event with her sister Bri and Galecki, 40, joined them inside the party. The trio was spotted chatting in the VIP area, dancing, taking selfies and watching musical performances from Calvin Harris, Bloc Party and Walk the Moon.

Cuoco and Galecki dated for almost two years before splitting in 2010. Rumors of a rekindled flame have been swirling recently in the wake of Cuoco’s divorce from Ryan Sweeting. However, the pair have vehemently denied getting back together.

“So sorry to disappoint, but no home wreckers or secret flings going on here. Me and @sanctionedjohnnygalecki are just the best of buds – Leonard and Penny will just have to suffice!!!” Cuoco wrote on Instagram in October.

On their former romance, Cuoco told CBS Watch! magazine in 2010, “It was a wonderful relationship but we never spoke a word about it and never went anywhere together. We were so protective of ourselves and the show and didn’t want anything to ruin that.”

Shortly before announcing her divorce from Sweeting on Sept. 29, Cuoco gushed about Galecki’s relationship with her husband.

“Johnny’s actually one of my best friends. Ryan loves him, Johnny loves him,” she said on Watch What Happens Live. “It’s been a long time, so it’s great. I got lucky. It could have been horrible.”
