He knows how to turn up the heat!

Justin Bieber cranked the heater on his pool to make it a giant jacuzzi in Beverly Hills over the weekend, and the Canadian stud looked mighty sexy as he relaxed in his steamy surroundings! The only thing The Biebs was missing was a girl to get wet with him! Where was Hailey Baldwin? Or Kendall Jenner?

One person we know that is seemingly over sexy swims with JB is his ex Selena Gomez! The "Come & Get It" singer has been flaunting her new romance with DJ Zedd all over town, and it has to be making the "Boyfriend" crooner slightly jealous. "Her number one man right now is Zedd and she’s falling hard for him. He’s good at turning lemons into lemonade. Selena says Zedd makes her feel happy and peaceful, and that being with him is addictive — in a good way," a source dished to Hollywood Life. "In fact, when she’s with Zedd, she tries not to talk about Justin at all. She is determined to make it work with Zedd," the source added.

The womanizing singer could have Selena back in two seconds if he wanted her!
