Jelena shippers, it's the moment you've all been waiting for!

Justin Bieber and Selena Gomez are back together, Us Weekly reports. The on-and-off couple, who were recently spotted on video spending time together at their friend Alfredo Flores' birthday party, apparently had a weekend full of fun -- and reconciliation.

"Justin and Selena are definitely full-on back together at the moment," an insider tells the magazine. "They spent all day riding together on a Can-Am Spyder on Sunset Blvd. Justin drove while Selena sat in the back, holding onto him."

"He was incredibly sweet with her," the source adds, "and they looked super happy and in love."

Of course, it was later that night that the two celebrated Flores' birthday at Bootsy Bellows club in L.A., and Biebs' pal Khalil caught the two together on tape. At the party, Bieber and Gomez "looked like a couple," another source claims, saying they were "all over each other" at the party.

The romantic reunion comes just days after Bieber posted -- and then deleted -- a sweet pic of him and Gomez cuddling together. He had captioned the photo, "Our love is Unconditional."

While things seem to be back on now, a different insider is skeptical about the Jelena reunion.

"It is always on-and-off. Same story, every other week, every year," the source says. "Now they are together, next week they won't be."

Whether or not they are officially back together, the insider says that the two still have a connection.

"They never stop talking, even when you don't see them together -- that never changes," the source reveals. "They fight, take a break, and then get back together. No surprise that it happened once again."
