"Olivier and I still care a lot about each other and there's still a lot of love there between us. I still speak to Olivier and you never know what will happen in the future."
She also tackled the allegations on her personal website, saying: "It is grossly unfair to demonize an honest man."
Kylie - who battled breast cancer in 2005 - and Olivier's relationship was constantly tested by rumors of infidelity.
The 41-year-old actor was linked to Israeli model Sarai Givati - who he is alleged to have enjoyed a Parisian break with in November 2006 - and former 'Lost' star Michelle Rodriguez.
In 2005, he was spotted dining with actress Salma Hayek and George Clooney's ex, French model Celine Balitran.
On Saturday February 3, just hours after Kylie, 38, and Olivier announced their split, the actor was seen embracing actress Penelope Cruz at Los Angeles' Chateau Marmont Hotel - the same hotel where he fell in love with the 'Spinning Around' singer.

Penelope Cruz says she has been a 'rock' for Olivier Martinez.

Penelope told Britain's Daily Mirror newspaper: "Olivier and I have been
friends for seven years, we are very close. You can understand that it's a
difficult time for him right now, so I have been there for him to offer
support. And it was lovely seeing him the other day, it has been such a long
time."
The 'Volver' actress, who admits Olivier, 41, is a "charming man", insists
the lingering embrace they shared at Los Angeles' Chateau Marmont hotel on
February 4 was completely innocent.
Penelope explained: "He is a great guy, but no, nothing happened."
