Justin Bieber and Selena Gomez share look of love at friend's birthday party

Justin Bieber and Selena Gomez confirmed that they were very much back together as they were spotted kissing and canoodling over the weekend.

The on-off couple, who first started dating three years ago, attended the birthday party of Justin's childhood friend Ryan Butler on Sunday night.

Renting out a private room in the Lucky Strike bowling alley in Los Angeles, Justin threw his pal a fun-fuelled celebration but seemed to focus a lot of his attention on his Disney star love.

"He was seen kissing and flirting with his on-and-off again girlfriend, Selena Gomez," a source told E! News. "The group, of about 12 people in all, enjoyed some of Lucky Strike's Esteban's Nacho's Grande, Cheeseburgers and wings. Specifically, Justin was seen eating the Mac & Cheese bites."

While Justin and Selena have remained coy on social media about their rekindled romance, the young sweethearts certainly had an air of love about them in a photo that Ryan's model girlfriend Ashley Guindon shared on Twitter.

Justin and Selena's night out in Los Angeles comes one day after the pair enjoyed a date night in Las Vegas. The couple were pictured strolling around the Hard Rock Hotel, flanked by four bodyguards, before heading out to cheer on Floyd Mayweather in a boxing match.

Justin and Selena are thought to have reunited in June when they were seen out and about together, but it was only late August when the singer posted a photo of the couple aboard his private jet that the speculation intensified.

The pair's most recent break-up was in April and before that late 2013.
