The former American Idol star became stepmother to businessman Kendall Taylor's son Treyshaun, when they wed in their native North Carolina last year (15), and the couple is celebrating a new family member.

Treyshaun's girlfriend Kayla gave birth last week (ends28Aug16), and Fantasia is embracing her new role, nicknaming herself "Glam Mom".

She recently shared two side-by-side photos of the proud grandparents on Instagram, and captioned the post, "Jumped off the plane and went straight to see our new Baby Khoen OMG (oh my god)!! I'm so in Love never seen my Husband like this before... King Khoen we welcome you"

She added the hashtag, "#GlamMom".

Fantasia has two children of her own, daughter Zion, 13, and son Dallas, two, from previous relationships.
