While the Carter family gathered for the lavish affair, one member was noticeably absent — 34-year-old Backstreet Boy singer Nick, who was expected to walk his younger sister down the aisle.

The bride's twin brother Aaron was given the privilege instead, and the siblings were pictured arriving at the church with Angel looking stunning in a halter lace gown.
A wedding guest later posted an adorable snap of the brother-sister duo sharing a touching moment on the dance floor.

As the ceremony kicked off on Saturday afternoon at Newhall Mansion in California, the absent Nick and his own bride-to-be Lauren Kitt were celebrating their joint bachelor and bachelorette party in Las Vegas.
Nick tweeted a photo of their celebrations at the Palms Hotel and Ghost Bar, where the engaged couple were joined by a group of about 15 friends.

"It's about to go down at @palms just entered the room of ecstasy," wrote Nick alongside a snapshot of champagne and gift bags.
The chart-hitting star popped the question to his fitness expert fiancé a year ago last February.
"I had the ring in my pocket for two weeks," Nick previously told People, referring to the seven-carat diamond sparkler. "I was like, 'I don't want it anymore!' It was driving me insane. I just wanted to get it out of my hands and on to hers."
