The performer’s health has been a serious concern due to his ongoing battles with addiction, but now Bam Margera is reportedly fighting pneumonia at a hospital in San Diego, and the situation is bad enough that he’s been placed on a ventilator.While the skateboarder and Jackass stuntman was considered to be on the road to recovery earlier this year He would frequently leave before being returned to the facility by police.In September, shortly after yet another return to rehab, he reportedly made friends with an attorney who believed he could get the Jackass performer out of court-mandated rehab and Margera has been out since then, despite reportedly not having completed the treatment that was ordered by the court.A temporary healthcare guardian was reportedly set up as a way to help Bam, but it was incorrectly reported that Bam was under conservatorship, similar to what Brittany Spears had to deal with for years.Margera and his wife Nicole Boyd have separated and she’s seen at least some of the guardianship blowback as well."
