Born November 12 in Los Angeles, little Aden John Tanner came home with his parents Tia Mowry and Adam Houseley to a house full of love -- and a pretty swanky nursery to boot!

Though she once griped about having to consolidate her closet to make room for some of her husband's clothes, given the fact that his "man cave" was becoming Aden's room, first-time mom Tamera is pretty pleased with the nursery renovation.

"[The nursery] is amazing!" she enthuses in a preview from STYLE's Dec. 4 episode of Tia & Tamera. "When I saw the nursery, there's something that switches in your brain [that makes you realize] you're going to be a mom! It became all so real."

Touring Aden's new digs while still pregnant, Tamera, 34, and twin sister Tia can't get over the nursery's special touches perfected by their interior designer. Among the jaw-dropping accents? Cloud details on the ceiling and a painting of a baseball jersey featuring husband Houseley's No. 40.

As the sisters gush over the baby's room, a thought dons on Tia. "What if this baby grows up not liking baseball?!" she chuckles.

FOX News correspondent Houseley and his wife -- who tied the knot in May 2011 -- paid tribute to their fathers when choosing their son's moniker. "A for me. T for Tamera," the 40-year-old told his Twitter followers. "John [is both] our fathers' middle name."

In the time since welcoming her baby boy, Tia has also kept her Twitter followers up to date on her family. "Adam and I are very overjoyed with love and feel so blessed," she wrote on Nov. 14. "Being a new mommy rocks!"

Tia & Tamera airs Tuesday at 9 p.m. (EST) on STYLE.
