Remember when Tamera Mowry tasted twin sister Tia Mowry’s breast milk on an episode of Tia & Tamera? The sip from a bottle of expressed milk sent tongues wagging and blogs afire — and now the twins are planning to do it again.

Tia and Tamera Mowry, stars of Sister Sister from long ago, are going to soon both be moms. Tia welcomed son Cree on June 28, 2011, and now Tamera is pregnant with her first child.

During a recent interview, when asked if Tia will try Tamera’s breast milk this time around, the 33-year-old mom replied she would “do it is because I want to know who’s sweeter.”

In reaction a visibly pregnant Tamera scrunched up her face and said, “That is so gross.”
