Justin Bieber reportedly wants to prove to Selena Gomez that he is a ''better boyfriend'' now.

The 23-year-old singer recently rekindled his romance with the 'Bad Liar' hitmaker after their tumultuous five-year on and off relationship ended in 2015, and now that they're back on track, the star is said to be keen to show his beau that he's changed his bad boy ways.

A source said: ''Justin and Selena are great. They still spend a lot of time together, but are being low-key about it. They attend church service together, have dinner and just hang out. [Justin] is set on proving that he is a better boyfriend.''

However, despite their new romance going from strength to strength, the pair won't be in a rush to spend the holiday season together, as Selena's family are said to still be wary of the 'Sorry' singer.

The insider added to People magazine: ''Justin's family always loved Selena, but Selena's family is still not happy about her seeing Justin. Selena doesn't bring Justin to any family events. Selena is spending Christmas with her family. As of now, Justin is not invited.''

It comes after Justin's mother Pattie Mallette admitted she has a ''special bond'' with 25-year-old Selena.

She said: ''I don't know so much about their personal relationship because he doesn't share a whole lot, but I love her. I support anything [he does], if he loves her I love her, and I've met her and we have a special bond so I think she's precious. I can't really speak on their relationship, that's between them.''

And Pattie also insisted that being in a serious relationship keeps Justin more ''grounded'' in Hollywood.

She explained: ''I think anyone with real love in their life is more grounded. I think there's so much confusion sometimes and facade in this Hollywood world, and so it's important for us to find the ones that truly care and stick with them.''
