Meanwhile, Justin’s former NSync bandmates Lance Bass, JC Chasez, Chris Kirkpatrick and Joey Fatone are said to be furious they were left off the guestlist.

The night before, the group celebrated at a beach where they watched fireworks and listened to live music.
Following the nuptials, Justin and Jessica released a statement confirming their marriage and saying what a great time they had.
They said: "It's great to be married, the ceremony was beautiful and it was so special to be surrounded by our family and friends."
