Australian cricket star Glenn McGrath has proposed to his girlfriend Sara Leonardi, reports say.

According to News Ltd, McGrath, whose wife Jane died of breast cancer two years ago, is engaged to his 28-year-old Italian girlfriend of seven months.

His manager, Warren Craig has confirmed to News Ltd that the couple got engaged last week.

Ms Leonardi on Saturday was seen wearing a sparkler on her finger as she walked alongside McGrath and his two kids, James and Holly, near their Woolooware home in Sydney.

Jane McGRath battled with breast cancer for a decade before she finally succumbed to the disease. After her death in June 2008, her husband put up a charity in memory of her called the McGrath Foundation, which raises money to fight the disease.
