Justin Bieber and Selena Gomez spent a full day together Sunday ... from morning until night.
These are pics of Justin and Selena attending church services Sunday morning ... this after grabbing some grub together at Joi Cafe in Westlake Village.
The exes left together and later in the evening Justin showed up at Selena's doorstep.
We're hearing from sources connected to The Weeknd all is fine between him and Selena, but there's certainly a lot of smoke.
