And he's just getting started!
Get the rundown (below):
In fact, Selena has already traded Justin in for a newer, younger model.
The 21-year-old bindi-loving babe is now reportedly dating 17-year-old Austin Mahone.
Selena must REALLY have a thing for singing teen idols and no one would know that more than her BFF Taylor Swift.
YUP! Apparently Swifty thinks age ain't nothing but a number because she decided to introduce the babyfaced couple after Austin opened for her on her Red tour.
Anyway, considering there is clear evidence T-Swift isn't JB's biggest fan, we're sure she's happy Selena is canoodling with anyone BUT the troublemaker.
The freshly minted twosome have been trying to have been trying to keep their status under wraps, they can't hide anything from us! Over the weekend they were seen leaving the Beats Music event in El Lay separately, but they totez got into the same ride.
While we'd think the Come and Get It songstress would want to date someone older and more mature following Justin's recent reckless escapades, Austin seems super sweet and innocent.
If we didn't love our Selenita so much, we'd call her a cradle robber…
..but instead we'll call her a cougar! Ha!
