Kaley Cuoco picked just the right time to get that tattoo covered up . The star of The Big Bang Theory, who today is celebrating turning 30, shared a pic last week of herself undergoing the painful-looking process of having a sizable butterfly inked on her upper back. But if many didn't know, that was also the spot of her old tattoo, the wedding date of her and ex-husband, Ryan Sweeting. Cuoco filed for divorce from husband Ryan Sweeting in September after two and a half years of marriage. The actress is doing great after the break up with her still successful sitcom and also a new movie due in theaters in March.
