Naya Rivera talks Mark Salling's child pornography charges

Naya Rivera's heartbreak became relief when she heard last year's shocking news about ex-boyfriend and former Glee costar Mark Salling.

Giving insight into her state of mind upon learning that Salling, 34, had been arrested on charges of child pornography, she reveals, "I can't say I was totally shocked, but still – WTF?"

"My son's nanny actually told me about it when the story broke," Rivera explains in her memoir Sorry Not Sorry (out now). "Then I had no doubt that God really did have my back along the way."

The pair dated for three years while filming the hit TV show, but the 29-year-old says she was dumped by Salling in 2010 after his publicist insisted their public relationship wasn't good for his image.

"When Mark dumped me, I thought it was the worst thing ever," she continues, "but can you imagine if that didn't happen? And I was laying there in bed when the battering ram came through the door?"

Salling was arrested on Dec. 29, 2015, after the Los Angeles Police Department's Internet Crimes Against Children unit obtained a search warrant for his home in Sunland, California. The actor was then indicted this past May 27 on charges of receiving and possessing child pornography on his laptop computer and a flash memory drive.

"I think everyone should have that one relationship where you look back and ask yourself, 'What the hell was I thinking?' You'll learn something and you won't regret it," Rivera's excerpt continues. "Unless, of course, that relationship was with someone who had a sizable stash of child porn on his computer. Then, by all means, regret everything."
