Newlyweds Kaley Cuoco- Sweeting and Ryan Sweeting are in cloud nine after almost four months of marriage. The couple played some tennis together, which gave the Big Bang Theory star a chance to show off her new ink.

Kaley, who's 28-years-old, tattooed their wedding date on her back and the ink reads: XII XXXI XIII, write Too Fab. The tattoo of Kaley is a match with her tennis player husband Ryan's exact same roman numerical wedding date along with a "Kaley" tattoo has on his forearm, which the athlete revealed right after their wedding.

From the photos Kaley posted, the Sweetings were as "sweet" as can be. Too see a photo of Kaley's tattoo, see Perezhilton's article.

Sporting matching pink and black outfits, the blonde sweetheart posted their matching photo (shown above) with the caption: Had a blast playing a little mixed with @ryansweething tonight. A man who agrees to wear pink, is a very very good man :)"

The couple was decked in full pink and black with Kaley wearing a black tank-top, pink and black shorts, pink high socks and a pink headband. Not to be outdone by his new bride, the 26-year-old professional tennis player donned a pink shirt, black shorts, pink and black socks and the same pink headband as his wife.

The Daily Mail writes that this new tattoo is the 2nd for Penny, Kaley's character on the Big Bang Theory. The first is a Chinese symbol for faith that the actress had done on her lower back when she was a young 17-year-old.

Sweeting Romance

Kaley and Ryan wed on New Year's Eve in Califonia after six-months of dating. Donning a pink Vera Wang dress, the couple said their "I Dos" after a three-month engagement announced in September.

Daily Mail spotted the pair before their tennis match with Kaley getting very excited to see a friend's baby as they walked. Given the whirlwind romance of this pair, who seem to be enjoying marriage, a baby may be in the works sooner rather than later.
