Will Leigh finally be lucky in love with racing boss Mark?

IT looks like Leigh Arnold could finally have found her perfect match -- in the form of racing boss Mark Kershaw.

The Diary can reveal that the glamorous actress has become close with the well-to-do socialite after being introduced by mutual friends.

And the pair did little to stop tongues wagging when they were spotted looking extremely cosy together during a night out in Lillie's.

"Mark and Leigh seemed to be getting on like a house on fire," said a pal of the actress.

"They arrived separately but spent the whole night flirting and only had eyes for each other.

"They had a couple of drinks together in the VIP area and looked pretty smitten by the end of the night.

"They didn't seem to care who saw them and weren't trying to be discreet at all," they added.

The pint-sized beauty (30), who has been decidedly shy about dishing the dirt on her lovelife of late, declined to comment when contacted.

Ironically, just a week previously Mark enjoyed a night on the tiles at the celebrity club with his good pal Citywest heir PJ Mansfield and none other than Leigh's ex Marcus Sweeney.

Sweeney, the former owner of Dublin's Il Pomo D'Oro restaurant, quit these shores for the millionaire's playground of Dubai more than a year ago after getting a job in the marketing department of a construction company.

However, in recent months Marcus has become a more frequent fixture on the Dublin social scene, making regular visits home to the city.

He and ex-girlfriend Leigh, who dated for two years, initially attempted a long-distance relationship before deciding to call it quits last August.

Since their break-up, Leigh has failed to find a lasting romance, although she was linked to director Nick Thomas for a time.

Leigh, who recently starred in TV3's Celebrity Salon, is also said to have enjoyed a brief romance with Hollyoaks actor Emmett Scanlan, after the pair met on the set of her new flick, Charlie Casanova.

Meanwhile, her rumoured new flame, Mark -- who works with his father in their multi-million euro Clondalkin-based business, Manvik, has had no shortage of high-profile women in his life.

Kershaw was previously engaged to former blonde model Lisa Harrison, who now runs glossy magazine In! based in Belfast.

And just last March, the racing boss was linked to his good pal Xpose presenter Glenda Gilson, after the pair were snapped arm-in-arm during a night out.

The TV3 beauty was quick to rubbish the reports however, insisting that they are just good friends.

The Castleknock model later confirmed that she had found love in the arms of dapper Dublin businessman Rob Macnaughton.
