Melbourne, Jan 3: Shane Warne has fuelled rumours that he's back with his ex-wife after reports emerged that the cricketer celebrated the New Year with Simone Callahan and three children at a holiday house.

The Courier Mail has learnt that Warne was spotted outside his former partner''s holiday hideaway south of Melbourne only hours before his departure to fulfill commitments at the third cricket Test in Sydney.

The star bowler''s late-model black Mercedes was parked in the driveway of the property for the entire New Year holiday.

Also, other friends were spotted leaving the house after low-key celebrations the night before.

While the pair has made no secret they will remain firm friends, neither is yet to deny a rekindled relationship.

Less than a month ago, Warne and Callahan were seen looking at property together in the Melbourne suburb of Brighton.

They were married for 10 years but separated three years ago after a series of sex scandals surrounding the spin bowler.

Early last year the mercurial couple reconciled, with photos and video of Warne and Callahan canoodling in Fiji.

However, by last September the couple was exchanging public barbs again, with Callahan claiming a stray text message had confirmed her fears that he was cheating on her. (ANI)
