Lance Bass shared the first photos of his twin babies he and husband Michael Turchin welcomed via surrogate last week.

In the photos, posted on Sunday, the *NSYNC singer smiled beside his newborn daughter, Violet Betty, and son, Alexander James.

“Haven’t slept much in 5 days and I’m covered in ick but I’ve never been so happy!” Bass, 42, captioned the Instagram post, jokingly adding, “Now there are four of us in this house that wear diapers (hint: it’s not me or @michaelturchinart).”

The babies were swaddled and wearing adorable hats as they slept.

He also shared several other pics of their bundles of joy including one where they donned Green Bay Packers pajamas and another where Turchin was seen sweetly holding one of their little ones against his chest.

Last week, the “No Strings Attached” singer shared the exciting news that he and Turchin were officially parents.

“The baby dragons have arrived!!  I can not [sic] express how much love I feel right now. Thank you for all the kind wishes. It meant a lot,” Bass said at the time.

Turchin, 34, also shared in celebrating their new arrivals, writing on social media of their twins, “They’re pure perfection and yes that includes the dozens of poops we’ve already dealt with. Our hearts our full!!! Thank you everyone for the well wishes.”

They announced that they were expecting twins in a Halloween-themed video in June.

The couple had selected their surrogate back in 2018, but the process took much longer than expected.

“We had several friends going through this and it took a little while, but I think we’ve broken the record for how many donors we’ve gone through,” Bass told Page Six at the time, adding, “We’re on donor No. 6 right now, and we don’t even know if that one’s gonna work. So, it has been a lot longer than I thought.”

He also joked, “You would think I would get so many offers for eggs, but not many people have come to me with their eggs! I think I’m going to have to tweet it out right now!”

The former boyband member and artist tied the knot in 2014.
