Inside Damian Lillard, Pregnant Fiancée Kay'La's 'Comfortable' Nursery for Twins: 'So Excited'

Damian Lillard is gearing up for two new additions!

The 30-year-old Portland Trail Blazers star announced in August that he and fiancée Kay'La Hanson are expecting twins, a girl and another boy (Lillard and Hanson welcomed son Damian Jr., 2½, back in March 2018).

While nesting for their babies on the way, the couple teamed up with Pottery Barn Kids and set out to make a "comfortable and modern" space.

"Damian and I are so excited about the nursery for our twins," Hanson tells PEOPLE. "We wanted to create a space that was both comfortable and modern, with dark browns and creams."

Adds Hanson of the final result, "We love the way it turned out."

When he announced the pregnancy news back in August, Lillard joked about welcoming a daughter to the family. Lillard proposed to his longtime girlfriend in February during the NBA All-Star weekend at a private party. The couple has been dating since college at Weber State.

"I'm a DADDY DADDY now 😂😂😂... happy for another boy but this girl gone hit different," he wrote on Instagram at the time, along with a portrait of himself, Hanson and Damian Jr. all holding out two peas in a pod.
