Justin Bieber looked over the moon as he watched his father tie the knot with his new stepmom Chelsey Rebelo at a beach wedding in Montego Bay, Jamaica on Monday.
The 'Sorry' hitmaker looked over the moon in several official wedding photographs shared on social media.
In one he can be seen throwing his hands in the air as he rushed down the makeshift beach aisle, whilst in another, he had a huge grin on his face as Jeremy and his new wife Chelsey Rebelo took their vows.
Justin's new stepmother shared a photograph from their special day, which featured the pop star.
She wrote: "Yesterday was the most amazing day ever. I married my best friend! I love you! (sic)"
According to PEOPLE, Justin flew to Texas on Sunday to pick up Selena, 25, before they headed to the Caribbean together for the wedding.
Jeremy took to his Instagram account on the same day to share a picture of himself and Chelsey at the bottom of some airplane steps.
He also shared a photograph of his family in a minibus on the way to board the plane bound for Jamaica.
Justin and Selena's latest trip comes after they enjoyed a pre-Valentine's Day getaway to Lagna Beach earlier this month, where they are said to have resided at the luxurious Montage Hotel.
The pair have been on/off for years after they first started dating in December 2010 and then split in November 2012, but he is said to be glad about having a second chance with the singer.
A source recently said: "Justin wants to be a better man because he doesn't want to screw things up with Selena. He knows he's lucky to have this second chance and he's not taking it for granted."
