Big Bang Theory Season 10 star Kaley Cuoco has triggered big bang on social media when she went a little overboard on being sexy.

Cuoco got playful on the Snapchat account of her celebrity stylist friend Brad Goreski and showed off her bare left breast.  The actress was trying out the different filters of the app when she pulled one side of her bath robe while Goreski was looking. The Fashion Police host, sporting the funny old-man filter, was seen pointing to Cuoco’s boob in the snap.  Her exposed breast was covered with heart emoji though.

In a May 2014 interview with Cosmopolitan, Cuoco revealed that she underwent plastic surgery for breast augmentation at the age of 18. The blonde actress admitted that she does not regret her decision to go under the knife.

“It’s one of the best things I’ve ever done. I love them. I’m super happy. I would do it again in a heartbeat,” she told Cosmopolitan.

Cuoco is currently dating equestrian Karl Cook. She recently opened up about how happy she is with her new beau. Cook is Cuoco’s first serious relationship after she split with former husband professional tennis player Ryan Sweeting.

She also recently shared a clip of her, Cook and their friends while having a good time. In the video, the actress was seen on Cook’s lap and repeatedly kissing his cheek.

During the 4th of July weekend, Cuoco also sparked social media stir when she shared a photo of her dogs sitting on an American flag. She was slammed for it, which prompted the actress to issue an apology.

The actress will reunite with her 8 Simple Rules mom Katey Sagal in the upcoming season of the CBS show. The veteran will be playing the role of Penny’s mom, Susan, who will bring more craziness to the show.

The Big Bang Theory Season 10 will premiere on September 19 on CBS.
