Domino Kirke is saying hello to two.

Two months after her husband Penn Badgleyannounced they are expecting twins, the "Teething" singer shared how they're going with the flow while getting ready to welcome babies no. 3 and 4.

"Everyone is in the same boat, very, very fluid with it," Domino told E! News in an exclusive interview. "I think they're taking my lead. No one's holding on too tight. It's just an expansion—that's what we're here for."
