23-year-old Jourdan is a pro when it comes to modelling and strutting her stuff on the catwalk, as she has worked for the likes of Burberry, Victoria's Secret, Topshop and Calvin Klein - to name a few.
And she's even appeared as a mentor on a recent episode of BINTM too, helping the girls get to grips with a topless photo shoot on the beach.
So, having her seal of approval and support is always going to be a good thing for any aspiring model!
Speaking to Reveal at Virgin Media's V Festival on Saturday (17 August), Jourdan touched on the subject of BINTM and although her modelling commitments have kept her from following the competition religiously, she still has a favourite to win.
"I don't know what's going on because I just got back from New York yesterday so I'm sort of out of the loop as to what's going on," she admitted.
"Is Sarah still in the competition? Yay Sarah! I want her to win."
Self proclaimed country girl Sarah got off to a rocky start in the modelling competition, but is now looking like one of the strongest contenders.
Last week, the 23-year-old seriously impressed judges Elle Macpherson, Dannii Minogue and Tyson Beckford with her stunning TRESemmé photo shoot in Barbados and she has now made it through to the final five!
Maybe Jourdan's top pick could go all the way.
