Adam Levine and Behati Prinsloo expecting first child - report

Adam Levine's wife Behati Prinsloo is reportedly pregnant with their first child.

The Victoria's Secret model is believed to have just entered the second trimester of her pregnancy and is due later this year (16), according to Eonline.com.

"She knows what she's having and she's very excited," a source tells the publication.

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."

Adam and Behati have yet to comment on the reports, but he recently revealed his secret to a happy marriage to newly-engaged The Voice winner Jordan Smith.

"Listen to the woman, man," he advised. "She's always right. Even when you don't always think that's the case, make her feel like it is. Trust me."

The couple is blissfully in love now, but its first meeting was slightly uncomfortable.

"We kind of started talking over email, back and forth for months," Behati explained. "I was kind of making fun of him. We talked over email for such a long time and then went to L.A. and we met for the first time.

"When we met finally, face to face, he was shooting the boxing music video, One More Night, I think it was, so he had gloves on. And I walked through the door and was like, 'What am I doing here?' And he had his gloves on and was like, 'This is awkward, hi!'"
