Cody Simpson's ex-girlfriend Gigi Hadid is showing the pop star what he's missing by baring all for a new fragrance ad.

The Sports Illustrated Swimwear Issue model has stripped off and posed on all fours to promote the new Tom Ford Velvet Orchid perfume, with her arms and legs carefully placed to preserve her modesty.

The 19 year old debuted the image on her page on Wednesday (02Jul14), adding the caption, "TOMFORD Introducing the new fragrance, Velvet Orchid #TFVelvetOrchid (sic)".

Hadid split from Simpson in May (14), but the Australian singer, 17, recently revealed he would be interested in rekindling their romance in the future. He said, "I definitely don't imagine it being over for good. We're still really good friends and we chat. We just had to slow it down."

The pair had been dating for less than a year.
