They are in Jamaica for Jeremy Bieber’s nuptials to his longtime girlfriend Chelsey Rebelo.
But it was Justin Bieber, 23, and Selena Gomez, 25, who looked like the newlyweds as they packed on the PDA during the wedding reception in Montego Bay on Monday.
The lovebirds couldn’t get enough of each other and were spotted kissing and cuddling as they stole private moments away from the other wedding guests.
Justin’s dad Jeremy, 42, tied the knot with Rebelo, 29, in an outdoor ceremony.
The party afterwards saw guests slip into beachwear as they lounged at a resort soaking up some sun.
Modeling a plunging blue swimsuit Selena looked gorgeous and wore her brunette locks up in a messy bun.
She teamed the one-piece with a white gypsy-style skirt and some gold necklaces which drew more attention to her cleavage.
Bieber, seen shirtless in white shorts and a baseball cap, wrapped his arms around the Wolves songstress and went in for several kisses.
For the ceremony Selena stunned in a peach floral wrap gown which flashed her legs.
She wore her dark locks swept back in a pretty updo and layered dainty gold chains around her neckline.
The songstress put on a flirty display as she flashed her leg while standing at the bar and sipping on a fruity drink.
People reported on Monday that the Sorry hitmaker flew to Texas to pick up his on-again girlfriend on Sunday to head to the Caribbean.
Jeremy, a father-of-three, shared a post to Instagram of the bride and groom about to board their plane.
Last week Justin and Selena spent Valentine’s Day together enjoying a date at the Montage Hotel in Beverly Hills.
The couple – who originally started dating in 2010 – have seemingly gone from strength to strength after reuniting last year following Selena’s split from The Weeknd.
