Thousands of women who screamed with excitement at Sonny Bill Williams' topless scene during the opening Rugby World Cup match will be disappointed to learn he is no longer on the market.

Williams quickly reached heart-throb status after his All Blacks shirt ripped during the game and had to be taken off, revealing his impressive physique - much to the delight of the cheering crowd.

But the All Blacks pin-up has reportedly been dating a fellow athlete, 21-year-old Cantabrian Aleisha Berryman. The pair were snapped by Woman's Day grabbing a Chinese takeaway meal together, dressed down in trackpants and casual jumpers.

The magazine said Ms Berryman has become a "permanent fixture" in Williams' apartment in Christchurch, which he shared with his younger sister, Niall.

The two girls play top-level touch rugby together, which is how Williams, 26, met Ms Berryman.

She also studies medical imaging and radiography at university.

She told Sporting Pulse that she hoped to become a sonographer after she finished her studies and later she wanted to teach physical education.

Ms Berryman's family are also heavily involved in the touch rugby circuit.

Her younger sister plays for the national women's team and her father coaches the under-15 Canterbury side.

Williams moved to Christchurch last year when he was picked for Canterbury and the Crusaders, before being picked for the All Blacks.

However, he is not expected to return to play for the Crusaders next year after he said the Christchurch earthquakes left him unsettled and he wanted to be closer to his mother in Auckland.
