JoJo Siwa and Chris Hughes are taking their coupling from the streets to the sheets … snuggling up to one another in a new pic — and, it’s hard to tell if they’re wearing clothes!

Hughes shared a photo of himself and JoJo lying back underneath the covers. Her arms are wrapped around his chest, and she’s resting her head on his broad shoulders.

In return, Chris is smooching JoJo’s forehead as he takes the selfie — writing, “Sleeepinnn beauty” underneath the pic as a caption.

As you know … JoJo and Chris started getting close after meeting on “Celebrity Big  Brother” just a couple months ago.

Siwa broke up with her longtime partner Kath Ebbs after the show wrapped, and — while she claimed it had nothing to do with Chris — the pair started dating almost immediately.

Most recently, we saw Chris and JoJo embrace at Heathrow Airport in London … making it clear that they’re far more than “platonic soulmates” as they originally claimed.
