Stefani gave birth to Apollo Bowie Flynn Rossdale Saturday, Feb. 28.

While his name might seem a little weird, Rossdale said there's a reason for it.

Rossdale shared the news on Twitter Saturday afternoon and wrote, "Gwen Stefani welcome Apollo Bowie Flynn Rossdale (Bowie and Flynn = mothers' maiden names).

The tweet has since been deleted.

The rockstar couple, who have been married for 11 years, also have five-year-old Zuma and seven-year-old Kingston together.

Stefani revealed she was having a boy back on January 17 on Instagram. She shared a picture to her more than 185,000 thousand followers. She wore a flannel green and blue shirt unbuttoned with a white top inside. She held a crown and smiled.

Stefani also included the caption, "I was ready to hand over the crown. But I guess I am still queen of the house. #itsaboy #surroundedbyboys"

She also shared a picture of her baby shower filled with blue sweet treats and the letters B-A-B-Y filled with blue and white candies and the infamous cake.

The Don't Speak singer added the caption, "baby shower!!! can't believe i'm pregs. Thank u Shelli Azoff for a beautiful #girlyday=blessed"

Her celebrity friends Gwyneth Paltrow, Jessica Alba, Rachel Zoe, Nicole Riche and Chelsea Handler were there to celebrate Stefani and the baby at Hotel Bel Air.

Stefani never confirmed that she was actually pregnant, but instead let her growing baby bump speak for itself.
