It sounds like Tamera Mowry-Housely might soon be working on a Sister, Sister for her little son, Aden! The former child star only has one kid of her own, so far. Based on her latest Instagram post, we have a feeling that could definitely change in the near future.

Tamera, 25, and her husband Adam Housley welcomed little Aden in November 2012, so he just recently celebrated his first birthday. Now, it sounds like the former Sister, Sister star is thinking very seriously about baby #2.

On January 20, she posted an Instagram photo of Aden playing with her friend Jessica’s daughter. “I think Aden is ready for a sister @pilatesjessluengoHis love for your lil Emma speaks volumes. Lol” she wrote.

So Aden appears ready, but what about his parents? Tamera doesn’t say for sure, but it seems pretty clear that the thought of expanding the Mowry-Housely brood is definitely on her mind.

Back in October, her twin sister Tia said that having a second baby is “definitely” on her mind. "It's something that we're talking about on a daily basis, so … we'll see.” Tia also has a son, Cree, age 2.

With any luck, Tia and Tamera might even end up getting pregnant at the same time! The Mowry twins sporting twin baby bumps? That is something we’d love to see.
