Behati Prinsloo's baby bump made an appearance on hubby Adam Levine's Instagram page yesterday, but we almost wouldn't have known had the Maroon 5 singer not mentioned it!

"My two favorite laker fans," Levine captioned the snap of his wife lounging poolside, along with the a baby bottle emoji. She may be about 5 months along, but you'd never know!

It was confirmed last month that the couple, who got married in 2014, are expecting their first child this summer.

In an interview with The Lowdown last year, Behati revealed she couldn't wait to start a family. "I’ve always wanted a family since I was a little girl, a big family," she said. "I’m an only child, so I wanted like 10 kids ... for sure." We bet this is going to be one good looking kid!
