The Voice US coach is married to supermodel Behati Prinsloo and back in March, the Victoria's Secret beauty debuted her baby bump at the launch of her new Juicy Couture collection in New York City.
And just a few weeks following Behati's first major red carpet appearance since becoming pregnant, Adam joined in on the celebration Saturday by posting a sweet Instagram photo of his family.
In the picture, Behati is seen showing support for Los Angeles based basketball group the Lakers by wearing a baseball cap with the team's name inscribed onto it.
Considering she is in the initial trimester of her pregnancy, Adam acknowledged his spouse and their unborn child by writing in the caption to the photo: "My two favorite laker (sic) fans."He signed off the loving message with emojis representing a baby, a bottle and a basketball.
Adam and Behati wed in 2014, and the singer has previously spoken about his desire to start a family with the Namibian beauty. "If I had a kid tomorrow or in five years, that would be beautiful," he said in 2013.
"I don't know when that will happen. I don't plan."
However, he knows he wants a big family: "Like 17," he joked in 2014. "Is that reasonable? I love kids so much, though. I love seeing kids on the (The Voice) set, too.
"Behati is due to give birth to her first child with Adam later on this year.
