There must be something in the water.

Yet another celebrity is with child, this time it’s Tisha Campbell-Martin, who is two months pregnant with her second child.

“She just found out and is so excited!” Tichina Arnold, Tisha’s best friend and former Martin co-star, tells Us Weekly.

Tisha, 40, and husband Duane Martin are already parents to son Xen, 8 ½. The couple — who have been married for 12 years — are hoping for a girl, Tichina shares.

“She hopes to have a girl this time, and has said she would love to name her Derek. She has been wanting a girl for almost six years. Everybody is so excited!”

Congrats Tisha and Duane!
