Cara Delevingne has joked that bacon is her best beauty secret.

The 21-year-old model has an unconventional approach to skincare and claims her love of the fatty meat treat keeps her complexion looking so good.

Asked by Vogue magazine to reveal her favourite beauty product, Cara teased: ''Bacon. What do you mean it's not a beauty product? Wait till my bacon range comes out... And eyebrow gel, obviously.''

Cara's comment isn't far from the truth, however, since the fashion bible caught her scoffing bacon out of a paper napkin mere hours before taking to the runway at the Victoria's Secret Fashion Show last week (13.11.13).

The sexy tomboy is such a fan of the calorie-laden foodstuff that she was even pondering about whether to get it tattooed on her body earlier this year, asking her fans on Twitter, ''Should I get a tattoo of bacon or cheese?''

The brunette strutted down the catwalk in a sexy soccer player ensemble at the Victoria's Secret show, which also featured the likes of Lily Aldridge, Karlie Kloss and Jourdan Dunn.

Cara insisted the models are all good friends and there is never any negativity or snide comments backstage.

She added: ''That's the thing about this show, it's so nice. Victoria's Secret is really about celebrating women and what they stand for; the strength. It's not at all [bitchy]. We're a team - we're all here for the same reason, and we're all trying to make the show great.''
