WTF?! Willow Smith, 13, photographed in bed with shirtless actor, 20

Pictures have surfaced online of 13-year-old Willow Smith lying in bed with 20-year-old actor Moises Arias.

The photos, which feature on their mutual friend's Tumblr page, show the Enders Game actor sitting up in bed shirtless with Willow at his feet during Coachella festival. And well, there's just something a bit iffy about that, right?

The Tumblr page also features other black and white snaps of her 16-year-old brother Jaden Smith in bed with Kylie Jenner, also 16. As well as numerous snaps of 18-year-old Kendall Jenner frolicking around in a bikini.

Look, Jaden and Moises have been friends for a long time, so it's all likely to be pretty harmless. But it still has TheFIX wondering where the adults are in all of this!

But then again, they also let her release a single about having a summer fling when she was 12. So they're probably not too concerned. See the video in question below...

Talk about a child star in the fast lane!
