"Selena and Justin flew overnight from Dallas to Jamaica for Jeremy Bieber's wedding on Monday," a source told E! news. "Justin picked up Selena in a private jet, and they arrived first thing in the morning to Montego Bay. They spent the day with Justin's family at a resort catching up and getting ready for Jeremy and Chelsey to get married."
