Hey baby, hey baby, hey! It has only been seven weeks since Gwen Stefani gave birth to her third son, Apollo Bowie Flynn Rossdale, and this mother of three already hit the stage showing off her post-baby body, and boy does she look amazing!

The No Doubt lead singer made a surprise visit to Coachella — which was also her first official appearance since giving birth — where she joined Pharrell Williams on the stage to perform her hit song, “Hollaback Girl.” Gwen rocked a bejeweled black jumpsuit and her signature red lips.

The singer even took to Twitter to announce her return by saying, “Feels good to be out of the cave #Coachella2014.” And it feels great to have you back, Gwen!

Gwen, 44, and her husband of 11 years, Gavin Rossdale, 48, welcomed their third son this past February, who joins his already hip older brothers, Kingston, 7, and Zuma, 5. Even though Gwen had hopes to have a girl this time around, she seems to be more than OK with the fact that she remains the only woman in her growing family.

“I was ready to hand over the crown. but I guess I am still queen of the house. #itsaboy #surroundedbyboys,” the singer wrote on her Instagram when she announced the baby’s gender in January. We have to admit, that crown suits the original Hollback Girl quite well, and we’re happy to see her “out of the cave.”
