Kaley Cuoco and her boyfriend turned fiancé Ryan Sweeting were caught kissing at the 2013 Veuve Clicquot Polo Classic event at Will Rogers State Historic Park in Los Angeles.

"The Big Bang Theory" actress gave her future husband a big kiss on the cheek in front of the cameras.

Cuoco, 27, and Sweeting, 26, have not been shy about showing some PDA since news broke that they couple got engaged in late September after a three-month courtship, according to Us Weekly.

Just a couple of days ago on October 2nd the newly engaged pair was spotted holding hands while the Maxim model was filming.

While at the Polo Classic event Cuoco spoke about her new engagement. She said, "I'm excited, on top of the world, we're so happy!"

However, despite her quick engagement the bride to be is in no rush to walk down the aisle anytime soon. Cuoco said, "We are too busy to wedding plan," she added, "In a year we will start talking about it. We are enjoying being engaged."

Just a week ago Cuoco acknowledged that their fast engagement "seems a little crazy on paper, but it's what works for us."

She told Entertainment Tonight, "From day one I just knew immediately and it's been magic. We have all the same family friends. We grew up with the same people, we just never met. So I kind of feel that I've known him my whole life."
