Jelena may be back on! Off-and-on duo Justin Bieber and Selena Gomez were spotted together at the bar of the Montage Hotel in Beverly Hills, California, on Nov. 20.

In addition to spending some time with his former lady love, Justin serenaded the "Come and Get It" singer, as well as some other lookyloos hanging out at the bar.

A lucky bar patron posted a couple of Instagram videos of the 21-year-old singing to his paramour. The Canuck sang the Temptations' classic "My Girl" and his new hit song "Sorry."

The fan captioned one of the videos, "@JustinBieber singing my girl to @SelenaGomez....is this real? Pure magic."

The heartthrob has been doing a plethora of interviews for his new album Purpose and in several of them, he's been talking about his relationship with Selena. On Nov. 19, Justin told Ellen DeGeneres that rekindling the romance "could possibly happen."

Earlier this month, the Biebs opened up to Access Hollywood about his love for Selena, saying, "I'm never going to stop loving her. I'm never going to stop checking in on her." He continued, "We always respected each other and we still respect each other. ... I think we both gotta do some soul searching ourselves, and figure out ourselves before we can just try to figure out each other."
