A big congratulations goes out to Bush frontman Gavin Rossdale and No Doubt singer Gwen Stefani on the birth of their third son. Apollo Bowie Flynn Rossdale was born into world on Friday, Feb. 28.

In a Tweet (seen below), Rossdale, wrote, "Welcome APOLLO BOWIE FLYNN ROSSDALE  2/28/14  (Bowie and Flynn = mothers' maiden names)."

Apollo joins older brothers Kingston, 7, and Zuma, 5, in the Rossdale household. The Bush rocker also has an adult daughter, Daisy Lowe, 25, from a previous relationship with Pearl Lowe.

Bush's most recent album, 'The Sea of Memories,' was released in 2011 and featured the hit 'The Sound of Winter.' The band is reportedly working on a new album.
