Regis Philbin soon will have a part swapped out.
He announced on "Live and Regis with Kelly" that he's having a hip replaced because he's "been limping around here and it really is painful."
The surgery is set for next Tuesday, December 1, after the show returns to New York.
Philbin and Kelly Ripa are broadcasting from Las Vegas this week.
Philbin, who's 78, says after his hip heals he'll be back on the show next year.
