"Mad Men" co-stars Alexis Bledel and Vincent Kartheiser have officially tied the knot in a secret California wedding.

Bledel's representative exclusively confirmed the news to People Magazine and announced that Bledel and Kartheiser have exchanged "I do's" way back in June, in a private wedding ceremony.

The couple, who first met on the set of the hit series "Mad Men," first went public with their relationship back in 2012. Five months into their relationship, Kartheiser asked Bledel to marry him, the same publication noted.

A source close to the couple revealed, "Vinnie basically fell in love with Alexis while she filmed a three-episode cameo. He was definitely smitten with her from the beginning."

Bledel is also all-praises when it comes to her husband, the Daily Mail reported. "He's light and funny and has lots of energy on set. He keeps everybody energized as well."

Elisabeth Moss spoke with the publication last March and dished on her co-stars' on and off screen chemistry. "They are such a yin and yang. I've known Vinny for 12 years and Alexis is just the sweetest. I've never seen Vincent like this. It is really cool."

Bledel, who joined the cast of "Mad Men" during its fifth season, played the character of an unfulfilled housewife called Beth Dawes. Her character became romantically involved with Kartheiser's charcter, Pete Campbell. The former "Gilmore Girls" star then appeared in multiple episodes on the show, Hollywood Life noted.

The 32-year-old Bledel and 35-year-old Kartheiser has both been very mum about their relationship. However in April, in an interview Vulture, the first-time husband said, "We were completely professional. We never saw each other out. We never - it was nothing, it was just work."

Meanwhile, Bledel was in a long-term relationship with her "Gilmore Girls" co-star Milo Ventimiglia, from 2002 to 2006, according to the Daily Mail.
