The "Scandal" star reportedly welcomed daughter Isabelle with husband Nnamdi Asomugha at Cedars-Sinai Medical Center in Los Angeles on April 21, but she has refused to comment publicly on the new arrival.
However, the notoriously private actress decided to confirm the news to fans on Twitter while celebrating her first Mother's Day.
She writes, "Well ... I still wont talk about my personal life on here :-) But... I see your tweets. And I am filled with gratitude! XO #HappyMothersDay
"To ALL moms, all of you, of all kinds and in all ways... HAPPY HAPPY HAPPY MOTHER'S DAY!"
