Former cricketer Glenn McGrath has reportedly tied the knot with Sara Leonardi in a private ceremony in Sydney.

According to Channel 7 the event was held at their luxury waterfront Woolooware home at about 3pm AEST with the date kept a closely held secret, until now.

The property was almost completely shrouded by white sheets, with the pair believed to have signed a deal with a women's magazine, reports the Herald Sun.

There were just nine guests at the ceremony, with no cricketers believed to have been among the guests.
