MICHAEL ROSENBAUM, the original Lex Luthor on TV’s SMALLVILLE has confirmed he’s returning after a controversial hold-out to the series two-hour finale airing in May, The ENQUIRER has learned.

After months of will -he- or-won’t-he Rosenbaum finally relented, saying "I’m simply doing it for all of the fans out there who made Smallville the great success it is.

"I appreciate all of their passion, their relentlessness and even their threats. I can’t wait to hug the old crew back in Vancouver one last time and see all of my old friends once again….. Oh, and for Lex to become the bad-ass he’s destined to be."

Insiders have speculated that since Rosenbaum ankled the show back in 2008 ,as The ENQUIRER reported, that his career has been in the proverbial dumper and  he’s returning for one last hurrah to give his career a much needed shot in the arm.

exec producers/showrunners Kelly Souders and Brian Peterson said, ""It feels like the stars are aligning, literally. We couldn’t be more excited about having Michael back,

"And as far as the way he returns … there’ll be no doubt about how Lex becomes the great rival in Clark Kent’s life.

"He IS the villain of the story."

PLUS! Insiders tell The ENQUIRER that despite internal Warners/DC Entertainment  wrangling over the new Superman feature film, Smallville star TOM WELLING will finally appear in his legendary red and union blue Super-suit -one way or another – as the ultimate payoff to a decade long wait.
