Ricky Martin CELEBRATES 14-year-old Son Valentino’s Mustache in Haircut Photo

Ricky Martin's boy is becoming a man.

The Grammy Award winner, 51, posted a candid photo of his 14-year-old son Valentino "Tino" on Instagram on Friday, revealing the teen has grown a moustache in a photo of himself getting a haircut.

"Baby no longer," Martin wrote in the caption. Jwan Yosef, his husband, commented on the photo with three heart-eye emojis.

Martin and his twin brother Matteo were born in August 2008 through gestational surrogacy. Martin married Yosef, 38, in 2017, and they have two children, Lucia, four, and Renn, three, through surrogacy.

Throwback to Valentino's 14th birthday

Martin had previously gone surfing with his twin boys for their 14th birthday in August and shared photos from the outing. "Great beach day!" he captioned the photo.

"Birthday week begins for my oldest sons. Thanks to my brother Alecs for the good vibes of the day and teaching Matteo and Valentino to play with the waves," Martin added. "I'm the luckiest dad in the world."

In June, the "Livin' la Vida Loca" singer spoke to PEOPLE about life with his growing family and whether more children are on the way.

Will there be more kids for Ricky Martin?

"We are not pregnant," he said. "Right now, we're dealing with a pair of twins and a pair of Irish twins because Lucia and Renn are only nine months apart. And they're overwhelming, but we're strong and healthy."

Martin said that he and Yosef "want more" kids, adding: "There are embryos frozen. I remember every Sunday in my grandparents' house — we were 34 grandkids. I always said, 'One day, I want to open the door to my house and see many kids running at me saying, 'Daddy, Daddy, Dad!' That's something I've always dreamed of."
