Former 'N Sync member Lance Brass is planning a wedding, with some help from a former bandmate's wife.

Bass told Us Weekly at the LA Gay & Lesbian Center 42nd Anniversary Vanguard Awards Gala, that Justin Timberlake's wife, Jessica Biel, had some "really great ideas" for his big day with fiancé Michael Turchin.

"One really cool idea she had was that, on the invites, because we love our onesies, send out personalized onesies to all our guests so that at midnight after the reception it turns into a pajama party," he said. "How fun would that be? I think we might be doing that one. That was something we both loved."

Biel, 31, married Timberlake, 32, in October 2012. The entire group recently got together for Chris Kirkpatrick's nuptials to long-time girlfriend, Karly Skladany, and Bass said it was just like old times.

"It's very immature," he said. "We still pretend we're 16. A lot of fart jokes. A lot of old jokes that keep resurfacing. It's like nothing ever changed."

Bass added: "I'm so glad I went to Chris' wedding because I forgot about some of my old management company people. And then we were sitting there talking to Jessie Biel, too, and she gave us a lot of great pointers. And she had some really great ideas."

Bass, 34, who proposed to Turchin in Sept. 2013, said there few details in place for the actual day, but does know it will take place sometime next year. They couple said they are in hurry to get married.

"We've slowly but surely started planning it," he said. "It'll be a year from now. But it's a lot. It sure is a lot."
