In her new memoir, Selma Blair really sinks her teeth into her past.
The actress revealed she used to bite celebrities because she was nervous. In fact, the "Cruel Intentions" actress recounted a mouthy meeting with "Family Guy" creator Seth MacFarlane at a Las Vegas nightclub in 2004.
"I was starstruck," she wrote in Mean Baby: A Memoir of Growing Up. "What do I do in public situations where I admire someone, but feel as if I don't bring anything to the party? I bit him on the hand. 'Whoa!' he yelled. 'That really hurt.' It wasn't a disaster; I didn't break skin. But I soon hated myself."
A similar situation happened two years later when Selma introduced herself to Sienna Miller at a Los Angeles hotel.
"I couldn't begrudge her for any part she was winning over me," she wrote. "So, I grabbed her arm and bit it, playfully, as if it were an apple. Even as I held her forearm in my mouth I was aghast at myself. I thought, What have I gotten myself into? Or her? This is horrible behavior."
Sienna took the moment in stride, screaming, "Opa." However confused, the actress-model had to confirm that it happened, telling Selma, "You bit me, didn't you? You really did."
Still, the "Live By Night" star didn't "shame" Selma over the incident
"For this, in my book, she will forever be the belle of the ball," Selma wrote.
Selma's chompers also got her into trouble with Kate Moss, who didn't exactly like being bitten. Selma said the two women were pleasantly hanging out in a hotel suite in London and even took Polaroids together. It was then that Selma decided to revert to her old ways, and she bit the supermodel's finger.
"And because she laughed, I did it again," Selma wrote. "The second time, she did not laugh and exclaimed, 'That really f–king hurt!'" Taking matters into her own hands, Kate then punched Selma in the back, grabbed the "Legally Blonde" star's thumb "and crunched right into it."
"This was the first time I had any inkling of how much I might hurt people when I bit them," Selma confessed. "Immediately, I transformed into a shamed nursery school kid. 'Oh my gosh,' I whispered, 'I am so sorry.'"
