Lance Bass and his husband Michael Turchin are working on becoming a family of four.

While at the 24th annual LA Art Show Opening Night Gala to benefit St. Jude Children’s Research Hospital, Bass told Us Weekly that they’re in the process of trying for twins via surrogate.

“We’re already on donor number seven right now, so I think we broke a record with how many donors we’ve gone through. But it’s looking like this next one is actually going to work,” the former NSYNC member explained.

The couple is hoping for twins, one boy and one girl, because Turchin is a fraternal twin.

Us Weekly asked if the other NSYNC members would be on hand for parenting advice.

“Once we have them, I’m sure all the guys with their babies will come out and give us as much hints as they can to be a better dad,” Bass says.

As for Justin Timberlake, Bass only had good things to say about his role as a father.

“He’s just a loving dad. A lot of the dads get a lot of flak for not showing up in kids’ lives, always being gone, always being the one that works too much, and with Justin’s schedule the way it is, he’s still an incredible father. He’s a present father. And that’s hard to do,” Bass says.
