Fergie appeared on The Ellen DeGeneres Show in an episode set to air on Wednesday and the new mom talked about the reason behind her 3-month-old son with husband Josh Duhamel’s name, Axl Jack Duhamel.

The Black Eyed Peas frontwoman gave birth at the end of August and she’s now showing she’s settling into motherhood nicely.

Fergie told DeGeneres the name Axl comes from a dream she had. “I was in the audience at this festival. It was outdoors and it was all grimy and nobody knew who I was,” she explained, People reports.

Just as she was getting into the dream, the baby kicked her for the first time.

“On stage singing was Jim Morrison and then came Bob Marley and then Axl Rose. I was in heaven in this dream and I’m dancing and just getting into the music,” adding, “It was the first time my son kicked me in the stomach and it was like he was feeling the music with me.”

When she woke up her husband and told him what had happened in her dream, they brainstormed names and landed on Axl Jack pretty quickly.

Watch her explain the dream below:
