“The Voice” lovebirds Blake Shelton and Gwen Stefani are rumoured to be engaged or married after they announced their relationship to the public. And the hearsays continue when the couple “shows pregnant belly.”

Shelton’s mate and co-judge Adam Levine is expecting a child with wife Behati Prinsloo. But the Maroon 5 frontman shared a photo of his wife and Shelton’s “baby bump” on Instagram.

The singer captioned the photo with “Met these two sweet pregnant ladies today. Good luck @blakeshelton and@behatiprinsloo!” as Shelton hold his belly like a real pregnant lady.

Levine has done the “baby bump” thing months ago. When he posed alongside Prinsloo as she proudly shows her 2nd-trimester bump on social media as well.

But as for Shelton and Stefani, having a baby of their own might be difficult to do, considering her age. But as per OK! Magazine, the No Doubt singer is already pregnant with a girl.

“Supposedly they weren’t doing anything to prevent a pregnancy,” the insider said, quotes Hollywood Life. “It was something they’d both welcome, but they assumed that ship had sailed.”

While the public is waiting for a confirmation, Shelton and Gwen have been spending time together with her three kids- Kingston, 9, Zuma, 7, and Apollo, 2 – like a complete family. The country crooner has been bonding with Stefani’s son because it is also rumoured that he is about to propose to his lady.

“With Gwen, Blake has the family life he’d hoped to have with Miranda,” a source told Us Weekly. “Her kids love him as much as she does.” “Blake could propose to Gwen very soon. Gwen is everything he wants,” the source continued.

Whether or not the couple is expecting a baby or not, their love for each other has been obvious. Especially when the two did a duet of  Blake Shelton’s new song “Go Ahead and Break My Heart.”
