Ex Guns N' Roses drummer Matt Sorum is lifting the lid on his wild life in rock'n'roll in new memoir Double Talkin' Jive.
Among the many outrageous stories of excess and debauchery, one resulted in Sorum knocking out Full House star Dave Doulier, as he attended John Stamos' wedding to his first wife Rebecca Romijn in Beverly Hills, according to Page Six.
It all went down in September 1998, the year after he had been kicked out of Guns N' Roses by lead singer Axl Rose.
KO punch: Matt Sorum confessed he knocked out Full House star Dave Coulier during an after-party following John Stamos' wedding to his first wife Rebecca Romijn in September 1998
Sorum writes how, following friends' nuptials, Coulier invited them to an after-party at his place.
What would soon follow, would include heavy doses of alcohol and the rocker finding his girlfriend 'naked in the Jacuzzi with three random guys.'
The booze was flowing by the time the party kicked into gear at Coulier's home in Los Angeles.
'We started doing shots in Dave's kitchen almost as soon as we arrived,' Sorum, now 61, explains. 'After that, we moved on to cocktails. By that point, I noticed that I couldn't find my girlfriend, so I started looking for her.'
Searching around the home, it didn't take long before he stumbled upon her in that Jacuzzi bare naked with those three men.
Irate and ready to go on a rampage, Sorum noticed a flowerpot sitting in the backyard.
'I grab a flowerpot and throw it toward the pool, hurling a chair in the same direction, a second or two later,' he described the situation.

It's at this point that Coulier, best known for playing Joey Gladstone alongside Stamos on the hit sitcom Full House (1987-1995), tried to nip things in the bud and calm things down — to no avail.
Explaining his state of mind during that moment as his 'entire being being reduced to a mix of anger and despair', Sorum revealed how 'the guy doesn't even have time to put his hand on my shoulder before I've knocked him out,' he said, while referencing Coulier.
Although his memories of the evening are a bit hazy, Sorum does recall being thrown out of the after-party and into the street.
'I alternate between sweating and freezing, and at some point, it dawns on me that I'm naked,' he confesses.
Despite being naked, himself, the musician somehow managed to hail down a cab for a ride to his girlfriend's home, jump a fence to get into her house, and then quickly get dressed and find money to pay the driver.
