From Sister, Sister to Mama, Mama!

Hosted by Airest Newsome (of Dinner Party with Airest) the bash had such celeb guests as Jackee Harris (Tia's TV mom on Sister, Sister), twin sister Tamera, her The Game costars Wendy Raquel Robinson and Brittany Daniel. (Her husband, Battle: Los Angeles actor Cory Hardrict, was a surprise party crasher as well.)

The revelers noshed on grub cooked up by Gordon Ramsey (who has a restaurant at the London) plus custom cupcakes (topped with sugar booties and bottles!) and cake pops from Beverly Hills bakery Sweet E's.

Among the goodies that Mowry, 32, unwrapped? A stunning Petit Tresoir bassinet and baby shoes from Harris (Mowry cried!).

"Being around family and friends was definitely the highlight of my shower," Mowry tells Us. "Seeing my grandmother, best friend, and brothers and sister made it all seem so real that I am having a BABY!! No turning back now. I feel so blessed to surrounded by such love!"
