The Destiny's Child singer gave birth to a baby boy named Titan Jewell Witherspoon on Tuesday 4 November, her rep confirms.
In a statement, Kelly's rep told People that both mother and baby are "healthy and happy".
Kelly and Tim wed in Costa Rica in a small, intimate ceremony on 9 May.
Kelly announced her pregnancy some weeks later in June, after posting an Instagram photo showing Tim's shoes sitting beside a baby pair of Jordans. She captioned it: "I'll be stuntin' like my daddy."
In July, 'Dirty Laundry' singer Kelly said she couldn't wait to become a mother for the first time.
She told E! News: "I'm extremely excited. First of course for myself and my husband. We couldn't be more happy."
Congrats Kelly and Tim!
