Courteney Cox is continuing her super frank comments about David Arquette since their marriage ended, which she blames in part on his persistent bonage.
Her latest revelation? Thinking he had a gay men-seeking iPhone app.
Last night on Jimmy Kimmel Live, Cox described a recent discovery that had her wondering whether Arquette might be harboring a pretty big secret.
As she was buying songs on iTunes, the Scream 4 actress was perusing the purchase history of the iTunes account she and Arquette used to share.
She noticed someone had downloaded a slew of self-help books by author Eckhart Tolle - plus the iPhone app Grindr, used by gay men to meet others.
Cox was taken aback, she said: "Wow, what if you don't know the person you've been with for that long? [I wondered] if David's been buying Grindr!"
While Cox has been more than forthright, Arquette recently said he's getting increasingly "sick" of talking about their marital struggles all the time.
"All of this started because there are lies out there, and I wanted to be honest and speak my mind," said the actor, who already went to rehab.
