Justin Bieber & Selena Gomez Sweating Together, Staying Together Into the New Year

Justin Bieber and Selena Gomez were continuing their powerhouse romance into 2018 by hitting up a West Hollywood pilates studio to burn off some of the weekend margaritas and we got the sweaty photos to prove just how deep the love runs.

Justin and Selena went to Hot Pilates Wednesday afternoon but didn't have to get hot and bothered next to a bunch of regular folk, we're told they had a private pilates session.

Hot pilates sessions are between 95-100 degrees, and when the two singers left the studio they looked like they definitely got the full experience.

As we previously reported, Jelena spent New Years Eve together in Cabo San Lucas and then flew home with Selena's friends on a private jet. We were told there was some tension between the two on the way back, but apparently that's all water under the bridge.

It's great the superstar couple is beginning 2018 on a healthy note ... here's to keeping relationship, and fitness goals going strong!
