Kaley Cuoco and Ryan Sweeting kiss divorce rumors away as the cast of "The Big Bang Theory" season 8 got a big surprise from her husband ahead of her 29th birthday.

And the actress was the first to announce the big surprise as she wrote:

"Just when I thought no one could EVER surprise me, Mr Sweeting goes and does it. best birthday of my life / thank you to everyone involved- you know who you are."

According to E! News, the tennis player employed the expertise of Lauren Tatum Events in planning out the birthday party. Ryan Sweeting also invited Kaley Cuoco's closest friends at the Nobu restaurant in Malibu.

Lauren Tatum dished out the details of the party to E! as she said: "Kaley had no idea about the party and said it's the first time she'd ever been surprised. Ryan had been planning the party with me since July and is a GREAT planner! He wanted to make sure that every detail was tailored to everything she loves."

On November 21, Kaley Cuoco and Ryan Sweeting had dinner at Villa Blanca to try to keep their romance alive, said Just Jared.

The news came in the wake of the Kaley Cuoco and Ryan Sweeting divorce rumors being splashed in the tabloids weeks ago.

"Ryan knows that his tennis career is all but over. He doesn't have the ambition to compete for the big bucks. And why should he? He has a rich wife," a source told Star, according to Inquisitr.

"They've been fighting a lot because he tells her she's not a star at home," the source told the magazine, adding that the actress has been treating the athlete like a "house boy."

Kaley Cuocco's ego reportedly only grew larger when she signed the $1 million per episode contract to extend "The Big Bang Theory" for three more years.

Just like any Hollywood couple, divorce rumors will continue to hound Kaley Cuoco and Ryan Sweeting's marriage. For now however, they appear to be happy.
