All Of Me singer John Legend and wife, model Chrissy Teigen, announced on Tuesday that they are having a baby.

The couple, who tied the knot in September 2013, posted a photo of themselves lounging on a sofa, with a hint of baby bump seen on Teigen.

In her Instagram post, 29-year-old Teigen said that the couple have been "trying to have a baby for a while now".

"It hasn't been easy, but we kept trying because we can't wait to bring our first child into the world and grow our family," she said.

The surprise announcement comes after Teigen revealed on new talk show FabLife just a few weeks earlier, that she and Legend, 36, were seeing fertility docters.

"Honestly, John and I were having trouble. We would have had kids 5 or 6 years ago if it had happened, but my gosh. It's been a process," she said in the preview of the show.

In the show, Teigen and host Tyra Banks also shared their frustration in dealing with people who constantly ask about when they plan on having children.

"One day you're gonna ask that to the wrong girl who is really struggling and it's gonna be hurtful to them. And I hate that. I hate it. Stop asking me!"
