Deion Sanders -- Pray, Pray, Pray, Pray ... for Pilar

Deion Sanders swears he's still "cool" with his soon-to-be ex wife... even though his daughter SLAMMED her on Twitter ... and now the NFL great is begging his fans to "pray, pray, pray ... for Pilar."

Deion just phoned in to K104 FM in Dallas to talk about life since he filed for divorce ... and he started things off by apologizing for all of the nasty things his daughter Deiondra tweeted about Pilar last week.

"I apologize for my daughter" ... Deion said, adding, "She loves her father and she feels like I was being abused and misused and she lashed out."

In case you missed it, Deiondra called Pilar a "golddigging h*e" ... and insinuated she was screwing around with other guys behind Deion's back.

But Deion went on to explain, "The thing about it ... Pilar and I are cool, we’re cool. I mean we are cool, when I say cool, we’re cool."

Sanders also commented on the TMZ report that Pilar is still living in his insanely huge Dallas mansion ... saying, "We’re living under the same roof, that’s true ... I see her every morning. I say what’s up, what’s up girl?! It really is like that."
