TVGuide.com has your exclusive first look at the bride and groom below. It's been widely reported that Yeoman and Righetti will be leaving the show this season. Although CBS has not confirmed the couple's exit, creator Bruno Heller has called the pair's upcoming nuptials their happy ending.

"I don't think I'm giving away too much to say that by the time [the Red John story line ends], they are husband and wife," Heller told TVGuide.com recently. "I don't know your views on marriage, but [it's] most people's happy ending."

The Mentalist Season 6 premiere airs Sunday, Sept. 29 at 10/9c on CBS. Are you looking forward to seeing Rigsby and Van Pelt walk down the aisle?
