Lance Bass has asked Jc Chasez to sing at his upcoming wedding.

The former *NSYNC star is set to marry Michael Turchin on Saturday (20.12.14) and his ex-bandmate is planning perform with Kristin Chenoweth at their reception.

The 35-year-old singer said: ''I'm really excited that JC is going to [sing during] our first dance. It is, of course, very meaningful to me. He has the best voice I've ever heard in my entire life. And it looks like he might be doing it as a duet with Kristin Chenoweth.''

Lance recently admitted Justin Timberlake wouldn't be able to attend his nuptials, as the 33-year-old star will be performing in Atlanta, Georgia on his '20/20 Experience' world tour.

He told PEOPLE.com: ''I had no idea that anyone would be on tour so close to Christmas. So when we chose the date, I didn't even think to look at the schedules of any of the guys. It is sad, but he'll be there in spirit.''

But both of his other former band members, Chris Kirkpatrick and Joey Fatone, will both present for the event.

The duo's wedding is being filmed for an upcoming E! reality special that will air on February 5, 2015.
