Pop star Ricky Martin says he's counting on the Human Rights Campaign (HRC), the nation's largest gay rights advocate, to make the U.S. more welcoming for families like his.

Martin, who came out gay in March and is the father of twin boys Valentino and Matteo, welcomed guests as they arrived at the group's 14th annual National Dinner at the Walter E. Washington Convention Center in D.C. on Saturday.

“This is very simple. It took me a while but tonight I'm here and I want to say that I want to add my voice to yours. And I'm so happy to be part of this community,” a clearly elated Martin told the crowd.

“So as the father of two beautiful little boys, Valentino and Matteo, I'm counting on HRC to make this country a more welcoming place for families like mine. And more importantly for those LGBT families that struggle everyday to just get by.” (The video is embedded in the right panel of this page.)

In addressing the crowd, Grammy-winning Pink said she doesn't want distinctions between gay and straight marriages.

The 38-year-old singer is expected to talk for the first time about coming out gay in his new memoir Me, set to hit bookstores in both English and Spanish on November 2.
