Lance Bass and husband Michael Turchin welcome twins

Lance Bass and his husband, Michael Turchin, are officially a family of four. On Thursday, the couple revealed that their newborn twins were finally here.

"The baby dragons have arrived!! I can not express how much love I feel right now," Bass, 42, celebrated on Instagram. "Thank you for all the kind wishes. It meant a lot."

And while the NSYNC singer may have walked into fatherhood feeling confident, he revealed he still has a lot to learn, frantically asking his followers, "Now, how do you change a diaper??! Ahhhhhhhh!"

Turchin, 34, when sharing the delightful news to his personal Instagram, may have given away why his husband is asking strangers on the internet about diaper duty.

"They're pure perfection and yes that includes the dozens of poops we've already dealt with," he laughed. "Our hearts our full!!!"

The couple, who wed in 2014, also revealed the names of their two bundles of joy.

They have named their daughter Violet Betty and their son Alexander James. Their birth certificates state the infants arrived just one minute apart on Oct. 13.

Bass and Turchin announced that they were going to become parents in June, sharing that their journey to become dads entailed years of hardships with IVF, including a miscarriage last year.
