It's been reported that Kylie Minogue is back dating her ex-boyfriend Olivier Martinez, months after announcing her split from fiancé Joshua Sasse.

The Sun claims that the 49-year-old singer spent an intimate evening last Thursday with Martinez at the Chateau Marmont restaurant on Hollywood's Sunset Boulevard.

Kylie and Olivier were together for five years before they broke up in 2007 and the French actor is said to have been a huge support to the singer during her breast cancer battle in 2006.

A source told The Sun that the pair seemed loved up on a date earlier this week. "They seemed to be very much a couple," the source is quoted.

"Olivier arrived first, motorcycle helmet in hand, and walked around the restaurant before taking a corner table. Then Kylie arrived in a sexy knee-length denim dress.

"They both looked delighted to see each other and hugged before sitting down. During the dinner they appeared to be very touchy-feely and kissed a few times.

"Kylie was beaming from ear to ear and seemed engrossed in what Olivier was saying," the source added.

Kylie Minogue announced her split from fiancé Joshua Sasse in February Olivier Martinez finalised his divorce from actress Halle Berry last December.
