Allison Mack’s “Smallville” co-star Sam Jones III said the actress did not display any odd behavior when they were on set filming the popular series.

Jones said Mack had a boyfriend when they were filming and speculated that the actress may have gone off the deep end later on.

“While we were on the show, she had a boyfriend, so she was cool,” Jones told Us Weekly. “So, I mean, I guess she just became freaky, you know what I’m saying? I guess the inner freak just came out of her or something, but I don’t know man.”

Mack, 35, was arrested Friday for her role in an alleged sex cult tied to the self-help organization NXIVM. Mack pleaded not guilty to charges including conspiracy to commit forced labor and sex trafficking. She was released from federal custody Tuesday after posting a $5 million bail. As a condition of her bail, Mack is to have no connection with any current or former NXIVM members and will be monitored by an electric bracelet.
