Her mom might not like him, but his family approves of her!

Justin Bieber brought Selena Gomez as his date to his father Jeremy's wedding in Jamaica earlier this week, and fans couldn't resist snapping pics of the pair in their most private moments.

JB's dad wed longtime girlfriend Chelsey Rebelo in an intimate ceremony of about only 30 guests, and his famous son opted not to give a speech at the reception, but did serve as a groomsman.

The nuptials gave The Biebs some bright ideas, too.

A source tells X17:
    "Justin doesn't want to lose Selena ever again. He knows he wants to spend the rest of his life with her, and he knows that a proposal will put to rest all of her fears that he will break her heart. He's been talking to his pastors about getting engaged to Selena, and they're counseling him on the ins and outs of a God-centered marriage before he pops the question. You can pretty much count on them being engaged by the year's end."

They're definitely next!

Yesterday was the most amazing day ever. I married my best friend! I love you!
