The 28-year-old "Body Party" crooner gave birth to the couple's baby boy early Monday morning in Los Angeles, according to Page Six.
After much speculation, Ciara first announced she was pregnant on the View in January, with her 30-year-old rapper beau later confirming in March that they were expecting a baby boy. Ciara also was treated to a star-studded baby shower that same month thrown by her BFF La La Anthony and makeup artist Yolanda Frederick, which friend Kim Kardashian also attended.
This is the first child for Ciara and the fourth for her fiancé, who has three other children from previous relationships.
Ciara and Future are expected to tie the knot this fall.
