'Glee' Star Mark Salling's Strange Double Life Exposed

"Mark was always chasing after the youngest girls at parties," a source told In Touch magazine. "And when there were younger kids on set, he lit up and was very friendly to them. That doesn't mean someone is a pedophile, but now, looking back, it makes me shudder."

Salling, 33, was dating a teenager last year, and that raised eyebrows with many people.

"Mark used to brag about how it was fun to 'teach' her [about sexual behavior] because she was so young – it was borderline creepy because he was so much older," a source told the magazine.

"He's reeling from the whole thing," Hudson, who went to Mark's house to care for his animals in the wake of his arrest, told the magazine. "He's devastated. He's ruined."

Wells said he has known Salling for over 13 years.

"I don't know whether he's guilty of what he's been charged with, but I think there's got to be some sort of substance to the allegations," Hudson tells In Touch. "I don't think the police would have gone to his house and taken him to jail if he was completely innocent."

The person who reported a tip to the police, after being disturbed by images on his computer, was a former girlfriend. Wells said he wouldn't be surprised if a woman wanted to seek revenge over the way Salling treats women.

"I wouldn't say he's been in any lasting relationships — I'd call him an opportunist," says Hudson. "With his fame, he gets women whenever he wants."

Wells believes that bad decisions have brought Salling to this point in his life, and it's sad.

"I think he could have made wiser decisions," Hudson says of his friend, that could face up to 10 years in prison, "to not bring him to this point in his life."
