Dan Single sleeps three hours a night

Ksubi founder Dan Single ruffled feathers this week when he took a swipe at his ex Pip Edwards - perhaps it's because the overworked designer is running on empty?

Dan told Pedestrian TV in a Facebook Live video interview that the worst decision of his career was "working for General Pants."

Fans took this as a clear stab at his ex (and mother of his son Justice) who is GP's design director. The pair were once fashion's It Couple but split in 2008.

Dan, who now co-designs luxe PJs with his wife Bambi, told Yahoo7 Entertainment at the TEN PIECES MBFWA show he had no comment about the Pip drama but explained he has been working so hard he's averaging three hours sleep a night.

But he's got a hot tip for those feeling a little haggard after Fashion Week.

"I did an ice face mask the other day," Dan said.

"I put a whole bucket of ice in a bowl and put my face in it because I was so tired."

The fashion designer and his model wife Bambi Northwood-Blyth launched their new sleepwear range P.Jame on Wednesday but that doesn't mean Dan's getting much shuteye.

"I'm averaging about three hours a night sleep," he admitted.

Maybe post Fashion Week Dan will finally get a chance to snooze?
