Diamond Hints Gosselaar Took Steroids

In his tell-all memoir, Behind The Bell, Diamond spills details about off-screen sexual encounters between the high school actors, their hard partying ways and alleged drug use.

He recalls one episode of the programme, in which the gang filmed an anti-drug public service announcement.

Diamond writes, "I just can't help but think of all the off-camera drinking and recreational drugs being indulged by cast members during that time... I could smell a certain 'smoke' wafting from the crack (underneath castmates' dressing room doors)."

He singles out Gosselaar in another section of the book, suggesting he took steroids to make his muscles look more ripped and toned for 1994's spin-off Saved by the Bell: The College Years.

Diamond adds, "He suddenly exploded with manliness, loading 25 pounds of muscle on his once-scrawny frame in, oh, about a month."
