Selena Gomez just released her music video for "Good For You," and it's a little bit mopey, but she looks totally hot!

“I’m so happy to finally share the video for #GoodForYou featuring the initial stripped down version of the song,” Selena tweeted. And she's not kidding about the whole stripped down thing -- not only is she topless in her shower, but at one point she appears to be wearing nothing but a white tee and a bucket of water! You KNOW Justin Bieber is watching this on repeat...

And speaking of the Biebs, he was at the same club as Selena last night, and it was NO mistake. Bieber was attending the launch party for manager Scooter Braun's latest client, Tori Kelly, so it's pretty clear that Selena knew exactly what she was getting into when she showed up. We're just not sure why she left with Ed Sheeran though -- why not stick around a little bit longer and try to hitch a ride back to Bieber's party pad? Maybe she's just trying to play hard to get? We're VERY curious to see where this goes...
