Adam Levine opened up on that comical photo where he pretends to have a baby inside him.

Last week, the singer posted a photo with his wife, Behati Prinsloo, as they stand in side shots taking a mirror selfie that shows their pregnant bellies-- but, of course, only one of them is actually pregnant.

On Tuesday, Extra caught up with Levine where it was noticed that he didn't look as expectant there as he did in the photo.

"Well, I was pushing it out a little to accentuate my bump," he said.

The man's diet might be a bit off right now, but he still had a good time taking the picture.

"I'm definitely eating a lot of stuff that I don't normally eat, but it's fun to pretend like you're pregnant," he said.

Levine and Prinsloo are expecting a baby girl who is likely to be born this fall. As for what they plan on naming her, the singer said they have a "long" list right now.

"How do you name your best song?" Levine added. "We'll figure it out."

Rumor currently has it that Levine's friend and co-judge from The Voice Blake Shelton might be the baby's godparent.

"Blake has already volunteered to be the godfather, so he can show their little one the ropes," a source told Hollywood Life.

The site also mentioned that Shelton and his girlfriend Gwen Stefani might be throwing Levine and Prinsloo a shower for their first child.

"Blake said he wants to throw a baby shower with Gwen," the source revealed. "He was half-joking, but he seems like he wants to be involved and be there for Adam, all jokes aside."

Levine and Prinsloo have been married for more than a year now.
