How Grant Hackett sank his career

GRANT HACKETT'S POST-SWIMMING WOES

PENTHOUSE TRASHING: A drunken domestic meltdown after Derby Day celebrations in 2011 was the first example of a dark side. His wife Candice Alley called police after Hackett reportedly went on a rampage through their apartment, smashing furniture and photo frames and upending a grand piano.

Westpac dumped him as a brand ambassador after the incident, while a children's charity also cut ties.

BITTER DIVORCE: Hackett was kicked out of the marital home in 2012 following a drunken night out after the Logies. His high-profile marriage to pop star Alley ended in flames with both sides battling over prenuptial agreements and custody of their twins, Charlize and Jagger.

LOST IN THE CASINO: Disoriented and drugged up on sleeping pills, Hackett was photographed in 2014 wandering the foyer of Crown Casino barefoot and barely dressed, while searching for his four-year-old son who had gone missing.

REHAB: Hackett checked into rehab-for-the-stars facility, The Meadows in Arizona, for five weeks in 2014 to kick his addiction to the powerful Stilnox medication, a hangover from his competition days. Upon his return to Australia, Hackett told media he was ready to get back on track with his life.

INFLIGHT INCIDENT: Anger issues erupted again in April 2016 on an interstate flight, where the swimmer reportedly groped and tweaked the nipple of another passenger and yelled abuse. Police met Hackett at the terminal where he was questioned. The incident throws into jeopardy Hackett's role as mentor to the Rio Olympics swimming team.
