The Maroon 5 singer shared a picture on Instagram of the Victoria's Secret Angel in a red bikini showing off her growing baby bump, almost a month after it was reported the pair were expecting their first child together.

Referring to his wife's baseball cap, he captioned the image: "My two favorite laker fans.(sic)"

The 'Moves Like Jagger' hitmaker previously hinted at his happy news with an Instagram picture of Maroon 5-themed baby items, which he captioned: "Yeah. we sellin' bibs now.(sic)"

Adam, 36, has previously spoken of his desire to have a big family.

The 'Voice' coach joked just a month after he and Behati married in July 2014: "We're definitely going to do it.

"I want to have 100 kids. I want to have more kids than would be socially responsible."

And the 'She Will Be Loved' hitmaker - who has been in a relationship with Behati for nearly four years - recently joked again of how he wants to have lots of kids because he always enjoys spending time with them on the set of 'The Voice'.

He said: "[I want] like, 17. Is that reasonable? I love kids so much though. I love seeing kids on the set too.

"Yeah, we're gonna do it at some point in the not-so-distant-slash-undisclosed-slash-I-really-have-no-idea-big-question-mark future."
