Behati Prinsloo took to social media in recent days to wish her husband, Maroon 5 front man and coach on The Voice, a very happy birthday.

“Happy birthday to the love of my life,” the Victoria’s Secret model captioned an adorable shot of her riding piggyback on Adam. “Everything is boring and meaningless without you!!! ? #besthusband ?.”

Next year on Adam Levine’s birthday, there will be one more person in their family. Behati Prinsloo is pregnant, and the two couldn’t be happier about their first foray into parenthood.

Just a few days ago a source told E! News that Behati Prinsloo and Adam Levine already know what they’re having–but they’re not divulging anything yet.

“She knows what she’s having and she’s very excited,” the source said.

While Behati Prinsloo no doubt showered Adam Levine with birthday gifts, it seems the best is yet to come. No due has yet been revealed for the happy couple, but Behati is in the beginning of her second trimester, so that means she still has several months to go.

Many fans wished Adam Levine a happy birthday via social media this week, too, but it’s likely none of those messages meant as much as the one Behati Prinsloo posted for him.
