He's not sweating the fact her whole family hates him!

Justin Bieber paid Selena Gomez a visit at her home last night, and it's pretty clear he's not letting her mom come between them. The "Come & Get It" songstress' mother Mandy Teefey was recently hospitalized for stress over their on-again relationship, and now SG and Mandy have unfollowed each other on Instagram. The feud is heating up!

It sounds like The Biebs is ruffling more than a few feathers by being back on the scene, but his lady love is choosing him over everyone.

"Justin came back into her life. Emotions were high after the surgery, so it was the perfect opportunity for them to reunite. Justin and Selena really bonded over their faith and feel like this is a brand new relationship -- even if other people don’t see it that way," a source dished to ET.

"They are very serious. They are in this for the long haul. They may be young, but don’t forget, both their parents married young and had children young, so this is normal to them, plus they’ve already accomplished so much career-wise. They’re at a point in their lives where marriage and kids are definitely on the table," the source added.

If we were a parent we wouldn't be too thrilled about the "Sorry" crooner dating our daughter, either!
