Kaley Cuoco took a bold step and flashed her breast on a social media application. The Big Bang Theory actress stunned fans by posting an image of her bosom on her close friend and celebrity stylist Brad Goreski's Snapchat account.

The 30-year-old actress pulled open her pink dressing gown and exposed her right breast and Goreski used a red heart sticker to cover his friend's modesty.

Cuoco recently opened up about love life and her boyfriend Karl Cook in an interview with People Magazine. She said, "It's funny, he's either the one riding or it's me, so we're rarely doing it together. But recently we did go on a little trail ride date. It was adorable. "

"We hadn't really done that yet. One is usually cheering for the other so that was kind of cute to go out together. We totally held hands. It was very dorky!" she added. Cuoco also revealed that they rode into the sunset together and that the date was just like "a storybook ending."

The actor who plays Penny in The Big Bang Theory spoke about finding love and sharing that special connection with her equestrian beau. She explained, "When you share something so special, some sort of connection — for us, it's horses, but anything two people share — you have that common goal and you know that you want the same things in life, day to day, and in the future. It just sets you on a better path. Having a lot in common is really important and we definitely have a lot in common. I think that that's what makes us so strong and really happy."

Cuoco, who is currently filming the 10th season of the hit CBS sitcom, filed for divorce from pro tennis player Ryan Sweeting in September 2015. She and Cook have been dating for a couple of months now.
