When Charlotte Kemp Muhl was a little girl growing up in Georgia, her classmates had a couple of pet names for her, and she shudders just recalling them.
“They used to call me Duck Lips,” she says, “and also Rabbit Feet, because I have really big feet. And the problem with me is that — on top of having big feet — I’m just kind of dirty and more like a boy.”
The fashion world, however, would certainly beg to differ. Since she started modeling at age 12 as Kemp Muhl, her sultry, sensuous pout has graced countless magazine covers around the world, and been featured in campaigns from noble houses like Dolce & Gabbana, Sisley, Hilfiger and Donna Karan.
For several years, she was the Vidal Sassoon spokesmodel for Asia.
But Muhl, 23, is much more than a pretty face. With her equally famous boyfriend Sean Lennon, the singer-accordionist launched an ethereal duo called the Ghost of a Saber Tooth Tiger — they play in San Francisco on Tuesday — and an entire label, Chimera Music, to release their recordings — like the album “Acoustic Sessions.”
Also an actress who would rather write and direct, she’s currently working on several top-secret screenplays with Lennon.
“I definitely have a lot of things on the burners,” she says.
In GOASTT processionals like “Jardin Du Luxembourg,” the smoky-throated Muhl plays Brigitte Bardot to her guitarist/co-vocalist beau’s Serge Gainsbourg.
With her childhood chum Eden Rice (who helps the team design their website and Max Ernst-ish merchandise), she’s re-recording songs they penned as teenagers for Chimera as Kemp & Eden. “We fund every aspect of the label ourselves — it’s like a mini-Motown or something,” she says.
Muhl met Lennon at Coachella when she was 17. They instantly hit it off, bonding over their equally surreal upbringings.
“Then he went off on tour, and we ended up developing this really intense written relationship, through postcards, letters, e-mails and texts, and started falling in love that way. So it was like an old-fashioned courtship.”
When Lennon found a play she had written at age 7 called “The Ghost of a Saber Tooth Tiger,” she adds, “he jokingly suggested that we start a band with that name. And somehow, it stuck.”
Muhl has done some exotic shoots over the years — riding Andalusian horses and skittering around a bullring with a real, and very angry, bull.
While the offers keep on coming, she says, “To be honest, I only model now for one reason — just to make money so I can re-invest it in our label!”
