Model Amber Rose has welcomed her second child into the world, and his name is Slash Electric.

The American star, who previously dated Kanye West and who has six-year-old son Sebasian with ex-husband Wiz Khalifa, gave birth to her son on Thursday.

It is her first child with music executive Alexander “AE” Edwards.

Edwards, who has been in a relationship with Rose since last September, posted a picture of himself on Instagram kissing the newborn.

The green-haired new father wrote: “Slash Electric Alexander Edwards.. the world is urs now (heart) thank u @amberrose for loving me so much that u put ur body thru it 2 bring my sun in2 the world.

“I could never be as strong as u.”

Perhaps referring to Guns N’ Roses rocker Slash, he added: “Slash a rockstar.”

Throughout her labour, Rose, 35, shared pictures on her Instagram story, including one of Edwards in medical gear along with the caption: “It’s time.”

Rose, who holds annual SlutWalk events in Los Angeles – which she says challenges rape culture and empowers women – was forced to cancel this year’s march in August because she had to “protect my energy and peace” while expecting her child.
