Kaley Cuoco Wedding Ring (Photo): Big Bang Theory Actress Debuts Ryan Sweeting Diamond

Kaley Cuoco stepped out with her brand new husband Ryan Sweeting and debuted her enormous diamond wedding band over the weekend.

The newlywed pair tied the knot on New Year's Eve during a lavish wedding that included the actress' pink wedding gown and an upside-down chandelier cake at the Hummingbird Nest Ranch outside Los Angeles.

Just days later, Cuoco and Sweeting sat courtside at the Jan. 3 basketball match between the Los Angeles Lakers and the Utah Jazz.

During the game, the "Big Bang Theory" star appeared jubilant while her husband kept an austere face watching his favorite team.

Moreover, Cuoco flaunted her brand-new wedding band, which features her square-cut diamond engagement ring between two bands of diamonds, according to Us Weekly.

The stunning wedding ring comes as no surprise considering Cuoco's wedding gown was a custom-made pink Vera Wang tulle gown that featured hand-gathered details bodice and hand applique Chantilly lace accents, according to E! News.

Furthermore, Cuoco and Sweeting's unique wedding cake amazed fans- the six-tiered cake from L.A.'s The Butter End hung upside-down from a chandelier.

"TY (thank you) #thebutterend for creating our magical chandelier cake," Cuoco shared with a photo on Instagram following her wedding. "Literally hanging above us. EPIC."

Meanwhile, Cuoco and Sweeting were not the only celebrity lovebirds in the stands at Friday's Lakers game. Ashton Kutcher and longtime girlfriend Mila Kunis were also spectators at the Staples Center, and the pair even posed for a kiss on the Kiss Cam.

Also, similar to Cuoco and Sweeting, Kunis and Kutcher are said to be on the fast track to marriage.

"They talk about getting married and having kids," a source close to the couple previously revealed to Us Weekly. "An engagement ring is imminent."

Kutcher's divorce from Demi Moore was finalized in November, nearly two years after the couple announced the end of their six-year marriage.
