The "Livin' La Vida Loca" hitmaker said: "My family's here. Jwan, I don't see you but my husband Jwan, I love you, my beautiful twins, Valentino and Matteo, they're also here, I love you with all my heart, you're my strength, you inspire me every day, you motivate me to keep doing what I'm doing and you guys are amazing kids. You guys are amazing. I love you. Lucia, my baby girl who is not here with us, she stayed at home with Grandma, but she's also the light of my life.

"And by the way, I have to announce that we are pregnant. We are waiting. Alright! I love big families."

Ricky made the announcement while he was accepting the HRC National Visibility Award for his advocacy of LGBTQ rights and his philanthropy.

Speaking about Ricky, HRC President Alphonso David said: "With his unique voice and passionate activism, Ricky Martin has used his international stage to advocate for LGBTQ people around the world."
