The Unfaithful actor supported the Spinning Around hitmaker throughout her cancer battle, before they went their separate ways in 2007.
Minogue found love again last year (09) with Spanish male model Andres Velencoso who, at 31, is nine years younger than the singer.
And now 43 year old Martinez has also bagged himself a younger beauty - 22 year old British model Rosie Huntington-Whiteley.
The pair has reportedly been a couple since meeting at a Victoria's Secret show in November (09) - and they cemented their romance by spending New Year's eve (31Dec09) in Martinez's native Paris, France, according to U.K. newspaper the Mail on Sunday.
A source tells the publication, "Rosie made her way out to Paris on Tuesday to spend New Year's Eve with Olivier, where he took her to a family friend's party.
"They have seen each other a couple of times since the Victoria's Secret show but this trip proves they are well and truly a couple."
