We wonder why The Biebs didn't join her for a little worship?

Selena Gomez headed to church last night, just hours after sweating it out at a private hot yoga session with Justin Bieber. The two recently returned from their New Years trip to Cabo, and it seems they're focused on fitness and faith in 2018.

The "Come & Get It" songstress and JB are going strong, and she doesn't care that her mom doesn't approve.

"Selena is avoiding her mother as her rekindled relationship with Justin intensifies. As Selena and Justin continue to rebuild their relationship, they have been spending more and more time together and things are getting serious. Selena is committed to making things work with Justin this time around but it is not always easy," a source dished to Hollywood Life.

"Relationships take work and Selena feels that her mother’s often critical words about Justin don’t help things at al. Mandy’s strong opinion of her daughter’s situation only makes Selena feel guilty when she just wants to be happy. Selena is dedicated to Justin and for now it is easier for her to keep her distance from her mom who she feels is often very judgmental of her relationship. Selena has asked her mom to back off with the commentary about Justin and she is hoping that her mom can give her space to follow her heart without feeling judged," the source added.

We have a feeling an engagement is coming soon!
