Enrique Iglesias and Anna Kournikova welcome 3rd child

Enrique Iglesias and former tennis player Anna Kournikova have welcomed their third child.

The singer announced on Instagram Thursday that their baby girl arrived Jan. 30, posting a photo of himself holding the newborn in the delivery room.

"My Sunshine," he captioned it.

Kournikova also posted two photos post-delivery: one of her cradling her daughter to her chest and another of her holding the baby as Iglesias kisses her forehead.

The baby girl, whose name hasn't been revealed, joins the couple's 2-year-old twins, Lucy and Nicholas.

Iglesias, 44, and Kournikova, 38, have been together almost 20 years.
