Bass, who proposed to Turchin in September, said he recently got some great wedding advice from Mrs. Justin Timberlake while attending the wedding of another bandmate, Chris Kirkpatrick, last week.
"I’m so glad I went to Chris’ wedding because I forgot about some of my old management company people," he said. "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."
So if Bass's wedding gets a little crazy, he'll have Biel to thank.
"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 added. "How fun would that be? I think we might be doing that one. That was something we both loved."
Bass said he and Turchin have started planning the wedding, but they're in no hurry.
"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."
