She's healthy, happy, and about to be back on with The Biebs! Life is good!

Selena Gomez dropped by Cedars-Sinai hospital transplant center for a check-up on her kidneys yesterday, and afterwards she grabbed lunch at Panera Bread in the valley and went for a relaxing bike ride. She certainly doesn't seem broken up about her split from The Weeknd, even though he was the one who allegedly called things off!

TMZ reports the "Starboy" crooner decided to pull the plug on their relationship even before the "Come & Get" songstress and Justin Bieber started hanging out again. Their busy schedules were making it impossible to be together, and he felt like their relationship had lost its passion. According to the site, they're still on friendly terms, and have talked on the phone a couple times since they went their separate ways. Perhaps that's why she didn't feel guilty about wearing his hoodie to go cycling?!

JB couldn't be happier that the brunette beauty is back on the market, because it gives him the opportunity to make her his girlfriend again!

"Justin is happy Selena is single. He hopes to regain her trust so they can get back together. They have so much to catch up on. They dealt with things separately this year that made them different people. It wouldn’t be surprising if they got back together," a source dished to People.

"It seems their relationship now is very different. Justin is certainly a much better person. He would be a better boyfriend, too," the source added.

Anyone want to take bets on how long it will take for Selena and Justin to officially become a couple? We say one more week!
