Fun appears to be the main ingredient keeping Kaley Cuoco and Ryan Sweeting's marriage intact-despite the two only being together for just over a year.

Kaley Cuoco's 'Big Bang Theory' Character Could Be Pregnant?

The couple, who shocked the actress' fans when they announced their engagement last Fall after only three months of dating-and then married on New Year's Eve-are still going strong despite their doubters-and judging by Cuoco's posts on Instagram, they're happier than ever as they close in on one year since first going public.

In fact, the two spent the entire past weekend together with their dogs, and even engaged in a game of tennis (Sweeting is a pro player), though Cuoco may have had reasons to playfully make fun of her husband because she hinted to fans that she managed to beat him at his sport.

Kaley Cuoco Says She And Ryan Sweeting 'Can't Wait' To Be Parents?

"This guy didn't know what hit him on the court today," she captioned a shot of the two on the court. While Sweeting looks directly at the camera, Cuoco sneaks up behind him with a tennis racket in her hand and makes a face like she is about to smack her husband in the back of the head.

The fun for the couple didn't end there, as their return home saw Sweeting get some sort of revenge, after his wife accepted the ALS Ice Bucket Challenge-and nominated friends Lacey Chabert and Ashley Jones, as well as her 8 Simple Rules co-star Amy Davidson-to also complete the challenge.

"Hi, I'm Kaley Cuoco-Sweeting . I've taken on the ALC Ice Bucket Challenge," she says in a video she posted on her page August 17. "I nominate Amy Davidson, and Lacey Chabert and Ashley Jones. Ahhh!!"

Her husband then proceeds to laugh as he douses her with a bucket of cold water-which causes her to shriek and then run off-camera afterwards.

The two are expected to make their next red-carpet appearance together at the August 25 Primetime Emmy Awards in L.A.-her series is up for its fourth consecutive Best Comedy Series nomination, while co-star Jim Parsons is up for his fourth potential Best Actor in a Comedy Series win. Bob Newhart and Mayim Bialik are also nominated for their work on the show.
