DREAM THEATER singer James LaBrie has ruled out the possibility of a reunion with the band's former drummer, Mike Portnoy, saying that Portnoy's replacement, Mike Mangini, "will be our drummer until the day that we finish doing this."

On July 30, Portnoy was asked by Chile's Radio Futuro whether he would one day be willing to reunite with DREAM THEATER and rejoin the band as their drummer. "Sure," he replied. "I would do it in a heartbeat. They are the ones that have closed the door on it. I've only needed a break, and I've had that break. So I'm ready, willing and able. But I honestly don't think they ever will; they've closed their door on it and I think they're too headstrong in having to prove themselves without me. So I wouldn't count on it. But my door is always open."

In a brand new interview with the same radio station, LaBrie was asked to respond to Portnoy's comments. "That possibility, I don't see it ever happening; it's not gonna happen," the singer replied. "Because, first and foremost, Mike Mangini is a full-fledged member of the band now, he's a phenomenal drummer and he's doing everything that we could possibly want as a drummer in a band. He's helping us realize exactly what we wanna do right now musically. And he will be our drummer until the day that we finish doing this, when we conclude. Mike Portnoy was a big part of our past, but I think that's where it's going to remain. He was a drummer from the past. And as far as presently and into the future, it will be Mike Mangini, and we all feel very strongly about that. He's an incredible drummer, he's an incredible asset to the band, and he is fulfilling our wildest dreams as far as what we're doing musically and what we're doing with each album. So that's the way it stands."

Portnoy, who co-founded DREAM THEATER more than 27 years ago, abruptly quit the band in September 2010 while on tour with AVENGED SEVENFOLD. He has since been replaced by Mike Mangini (ANNIHILATOR, EXTREME, JAMES LABRIE, STEVE VAI).

Portnoy played on AVENGED SEVENFOLD's latest album, "Nightmare", following the death of that band's drummer, Jimmy "The Rev" Sullivan, and toured with them for the entire second half of 2010.

Portnoy announced his departure from ADRENALINE MOB in June due to "scheduling conflicts." A replacement drummer has not yet been announced.
