13-year-old Willow Smith already beat him to the punch when it came to inappropriate photos of minors and twentysomethings, but 20-year-old Justin Bieber is just friends with his 15-year-old protege Madison Beer, right? Even though they're totally snuggling up to one another in the selfie above?

When we've chatted with Miss Beer in the past, she's excitedly told us how much she loves Bieber's music and how thrilled she is to be working on a duet with him, but we can't believe she doesn't have crush on the saggy pant-loving pop superstar!

But seeing as Bieber has posted photos of himself with several different ladies over the past week, maybe he's just doing this to toy with us? After posing with Kylie Jenner and model Yovanna Ventura in Las Vegas last weekend, several sites speculated that he had struck up a romance with one (or both!) of the girls, but a few days later he posted a photo of himself with Floyd Mayweather's 13-year-old daughter Iyanna and wrote, "I guess everyone I get photo'd with is automatically my girlfriend. This is my only gf @moneyyaya :p .. Had fun at the fight lil one see u soon.!"

Ha! But if he's not hooking up with any of those ladies, what's going on in his love life? Is he sexting on-again/off-again flame Selena Gomez? We must know!
