Liz Hurley and Arun Nayar are no longer together

Liz Hurley has revealed that she split from her husband Arun Nayar earlier this year.

The model made the announcement on Twitter yesterday following reports that she's been having a fling with Australian cricketer Shane Warne.

'Not a great day. For the record, my husband Arun & I separated a few months ago. Our close family & friends were aware of this,' she writes.

Liz and Shane, 41, were snapped kissing at a London restaurant last week and it's also claimed the pair spent 2 nights together at a hotel in the capital.

Shane divorced wife Simone Callahan in 2006, and a reported attempt to patch up their differences was not successful.

'Sadly and unfortunately, Simone and I split up a while ago, our close friends and family were informed at that time,' Shane writes on his blog.

'It is a private matter so we did not make it public. We remain friends and will continue to be good parents.'

Shane and Simone are mum and dad to Brooke, 13, Jackson, 11, and Summer, 8.

Liz, 45, married Arun in March 2007 after 4 years of dating.

She is mum to Damian, 8, with ex Stephen Bing.
