Congratulations are in order for Lily Tomlin! The actress-comedian and her longtime partner, Jane Wagner, married on Tuesday, Dec. 31, after 42 years together, her rep confirms exclusively to Us Weekly

The couple said "I do" in a private ceremony in L.A. on New Year's Eve. "They are very happy," her rep tells Us.

Chicago Tribune gossip columnist Liz Smith first reported the two had tied the knot in her column on Jan. 3. "It was an eventful New Year's Eve," she wrote. "My longtime friends, Lily Tomlin and her love, the writer Jane Wagner, got married on the eve of 2014...My wish is that their happiness will be as great as their combined talents."

Tomlin, 74, first met Wagner, 78, in 1971, when they collaborated on her comedy album This Is a Recording. The album went on to win the Grammy Award for Best Comedy Recording in 1972.

Since then, the couple have worked together on several other projects including the films Moment by Moment (1978), The Incredible Shrinking Woman (1981), and The Search for Signs of Intelligent Life in the Universe (1991).
