Neil Patrick Harris and Partner David Burtka MOCA Gala PHOTOS

How I Met Your Mother actor Neil Patrick Harris and his long-time partner David Burtka were on hand for the MOCA 30th Anniversary Gala on November 14 in Los Angeles. They have been in a relationship since April 2004.

Harris, 36, 'came out' publicly in People magazine in November 2006 amid rumors that he was in a gay relationship with actor Burtka. Media reports claimed Harris had pulled strings to land his boyfriend David a guest spot on How I Met Your Mother during season two, as Lily's old high school boyfriend.

The couple attended the Emmy awards together in September 2007 and openly acknowledged their relationship, which received a great deal of media attention at the time.

Harris and Burtka, 34, appeared on stage together for the first time in February 2008, singing a duet from Rent at a New York benefit. Harris refers to Burtka as "my better half" and "an amazing chef."
