Elle Macpherson and Bryan Adams are secretly dating, it has been claimed.
The Australian supermodel is believed to have been romancing the Canadian rocker for around a month.
The pair were seen sharing a passionate kiss at a private party Bryan hosted on Tuesday night following the launchof his new photo exhibition.
A source said: "They were all over each other, flirting outrageously and couldn't keep their hands or eyes off each other."
Elle - who has two children, Flynn and Cy, with her ex-fiance Arpad Busson - went to the launch of Bryan's new exhibition of photographic portraits, 'Modern Muses', in London members' club The Hospital.
But it was at the Mexican-themed after-party, held at Bryan's London home, where 44-year-old Elle showed her true feelings for the 48-year-old musician.
The source added: "They enjoyed a passionate kiss at his front door when they thought nobody was looking. They tried to hide behind the door slightly but were caught out. It was obvious all evening there was a lot of chemistry between them.
"Even when they weren't by each other's side they were constantly maintaining eye contact. They make a really cute couple."
Since splitting from Arpad in July 2005, Elle - who was previously married to fashion photographer Gilles Bensimon, who she divorced in 1989 - has been romantically linked to British actor Ray Fearon and Australian restaurateur David Evans.
