Behati Prinsloo and Adam Levine Have a New Pregnant Friend -- And It's Not Who You'd Expect!

Sorry, Gwen Stefani -- it's Blake Shelton who has to deal with pregnancy rumors now!

Adam Levine shared an adorable photo of his fellow Voice judge and his wife, Victoria’s Secret model Behati Prinsloo, on Friday, both of whom he described as "pregnant."

He captioned the cute pic, "Met these two sweet pregnant ladies today," the 37-year-old singer captioned the Instagram pic. "Good luck @blakeshelton and @behatiprinsloo!"

Earlier this month, the Maroon 5 frontman took to Instagram to show support for his wife, revealing that much like Shelton, he also has a baby belly. Levine and Behati both posed shirtless, baring their stomachs. "Week 20 and I'm finally popping! #impregnanttoo," he captioned the sweet pic.

Levine and Behati, 27, confirmed that they were expecting their first child together in April.

The bromance between Levine and Shelton is clearly going strong -- and so are the brotherly jabs! Last month, the 39-year-old country crooner joked to ET that he is "looking forward to Adam actually having to wake up before noon or one o'clock for the first time in his life, you know, to go change a diaper."
