Hackett steps out with Miss Teen

Almost two years after his public marriage breakdown, Grant Hackett has stepped out with a new flame 13 years his junior.

In photos published in Woman's Day magazine, the Olympic swimmer emerges from the surf alongside his latest love, Miranda Kerr lookalike and former Miss Teen Australia Tahlia Giumelli, with the pair both grinning from ear to ear.

At 20, Giumelli is much younger than her 33-year-old beau but Hackett has reportedly found solace with the beauty, right, following his bitter divorce battle with ex-wife Candice Alley.

Hackett hit the headlines in 2011 when photos surfaced of the couple's home after a domestic dispute, showing punched-in walls and smashed furniture.

The pair, parents to four-year- old twins Jagger and Charlize, announced their separation in 2012 and finalised their divorce last year.

Giumelli, Miss Teen Australia three years ago, recently greeted Hackett at a Sydney airport after he spent Christmas with his children on the Gold Coast.
