The beauty was just 14 years old when she began playing the straight-edged daughter of a Protestant minister on the family-friendly drama back in 1996.
But Biel confesses she went through a wild stage in her teens and her bad behaviour often sent show bosses into fits of rage.
She tells W magazine, “I cut my hair supershort and dyed it blonde. I had to apologise to (producer) Aaron Spelling for doing that. He wasn’t happy.
“When I turned 17 or 18, a really obnoxious friend sent a stripper to the set. I had to apologise for that too. The show was all about family values, and they took that position seriously. I was always apologising.”
Biel was written out of the programme during the show’s fifth season due to her alleged discontent with character Mary’s clean-cut image and growing tensions with producers after she posed semi-nude for Gear magazine at the age of 17.
