Apparently it's not impossible to keep a secret in Hollywood! Kaley Cuoco, star of the Big Bang Theory, did just that, when she pulled off a secret wedding to her beau of 6 months, tennis star Ryan Sweeting. Cuoco, 27, wed Sweeting, 26, in front of 150 guests at Hummingbird Nest  Ranch on New Year's Eve, wearing a bright pink sweetheart necked tulle ballgown designed by Vera Wang.

The starlet shared the news yesterday on Instagram, captioning her photo with "Last night I married my sweetheart!". She also shared pictures of her chandelier style cake, which was actually suspended from the ceiling!
