Amber Le Bon has given birth to her first child

Amber told Britain's HELLO! magazine: "I'm just so obsessed with him. I keep looking at him and think, 'how on earth am I ever going do anything ever again? And all I want to do is cuddle you and smell you...

"We had two names on our shortlist and when he came out, I said, 'I think he's a Sasha'. I've always loved that name.

"Echo is a name from Greek mythology, and we liked the way it flowed on from his first name."

Amber spent 40 hours in labour with Sasha - who weighed 7lbs 6oz - and was grateful to have both Ben and her mother by her side at London's Chelsea and Westminster Hospital.

She said: "I couldn't have done it without the both of them there; they were amazing.

"Ben was absolutely brilliant, and Mama was there to help, because I think it is quite exhausting and traumatic seeing someone you love in pain like that.

"I put a thunderstorm on the speaker, and I was chatting and laughing with the midwives, having a really lovely time. And then the last 10 minutes got a bit hairy, and I was whipped over to the labour ward for a forceps delivery, because Sasha was quite tired by then.

"Ben cut the cord, and they put Sasha on my chest. I was in a bit of shock, and I couldn't quite believe it, but I had this hot little human being on my chest, and I thought, 'Wow, he's really here'. But it took a while for it to sink in, and then I burst into happy tears and couldn't stop."

During her third trimester, Amber joined her dad on Duran Duran's US tour and her son has already shown himself to be a Duran Duran fan.

She said: "It was the last time I'd be able to do it without having to think about anyone else, and we had such a lovely time.

"I was quite big and pregnant at that point, and I wore sparkly dresses to all the shows and looked like a little disco ball, so we ended up calling the bump 'Sparkles', which was Sasha's name until he was born.

"Sparkles loves music - he's a mini-Durannie already. He was definitely kicking along to the older stuff."
