Where did this sudden interest in cycling come from?!

Selena Gomez whipped up some breakfast for Justin Bieber after their sleepover before heading out for a bike ride with her assistant this morning, and the singer looked a tad sleepy. We bet she didn't get much rest with The Biebs in her bed!

SG and JB are totally back together, and it's making everyone close to her nervous. That said, they are hopeful that his renewed interest in religion will make him less of an a**hole to her this time around.

A source tells X17:
    "Selena's family, especially her mom, are praying that she won't get her heart broken. Last time they split, Selena was a total mess and plunged into a depression, so they're hoping he will be good to her. Selena calls Justin her "soulmate" and everyone wants her to be happy, so they're on board with supporting the romance, but they all secretly wish she would just get over him for good."

We think it helps that the "Sorry" crooner doesn't have a world tour lined up anytime soon. Distance and temptation on the road were always Jelena's biggest problems, but now that he's settled in LA and doing nothing but going to church, chances are things will go smoothly... at least for a while!
