KATE MOSS’s £500,000 deal with sexy undies firm Agent Provocateur has been knicked – by an unknown model 14 years her junior.

The 34-year-old is replaced by ALICE DELLAL, 20, a half-Brazilian socialite with a nose ring.

Blonde Alice posed days ago for a secret photoshoot to be released in September.

It will overshadow a bridal lingerie campaign by Kate, who was picked for the role despite her cocaine-snorting shame.

A source said: “Everyone is stunned. Kate’s shots were really well received, but bosses thought it time to move on.

“They want a fresh new face and think they’ve found just the candidate in Alice.”

It is the second time the lingerie firm has dispensed with Kate. Her contract was not renewed last year amid rumours of a strained relationship with co-owner Serena Rees. But she was back for this year’s bridal ads.

Kate has also had a string of other snubs.

In March, NAOMI CAMPBELL took her place at Yves Saint Laurent, while AGYNESS DEYN, 22, supplanted her at Burberry.
