30 Rock actor Cheyenne Jackson married partner Jason Landau at a celebrity-filled bash in California this weekend.

Broadway performer Jackson and Landau (left), who got engaged in February, met in rehab last year while in treatment for alcohol. “We got sober together,” Jackson said. “Now we sing and we dance together. It blows my mind.”

“It was love at first sight and this is just the culmination of that.”

The couple’s dog, Billie Jean, played a special role in the inter-faith ceremony, which took place at a private estate in Encino, California.

Over 200 celebrity friends and well-wishers, such as Glee’s Jane Lynch and Modern Family’s Jesse Tyler Ferguson, turned out to help the couple celebrate their nuptials.

Jackson and Landau got engaged last February, 6 months after Jackson ended his 13-year relationship with then-husband Monte Lapka.
