Justin and Selena Have Baby Fever!

Belieb it or not, Justin and Selena seem to have caught baby fever — but, sorry to disappoint, it's not what you think.

Justin Bieber was out and about in West Hollywood on Thursday grabbing some sort of healthy-ish purple juice when he ran into a fan who wanted to snap a picture.

Instead of wanting the classic meet-a-celebrity-selfie, this fan opted for a pic of the Biebs and her baby. Justin obliged and let the fan snap a few pictures while he held the little tyke.

Yeah, it's super cute.

And just a few days ago, Justin's lady love, Selena Gomez, was spotted nuzzling a baby in a stroller while enjoying a day in the park.

Two celebrities, who happen to be in *lurrrrve,* snuggin' two different babies, only one week apart?

Just sayin' ...
