Ryan Seacrest is no longer feeling 29. 

After the Wheel of Fortune host shared earlier this fall that he had been feeling as healthy as ever as he faced turning 50 in December, he admitted that a subsequent injury has kept him from maintaining his past prime.

“That changed since I said that,” Ryan said in an exclusive interview with E! News at iHeartRadio’s Jingle Ball holiday special. “Now I have tendonitis. So it’s just it’s all going the wrong direction. As soon as I say that, put that in the universe, it all goes backwards.”

And while the 49-year-old was once feeling as fit as a fiddle, he noted, “Now I feel 50 and I’m not yet.” (For more from Ryan and other stars on the Jingle Ball red carpet, tune into E! News tonight, Dec. 9, at 11 p.m.)

The American Idol host may have overdone his healthy living—as he previously explained on Entertainment Tonight that he was feeling younger than 30 by “over-exercising, eating better,” and “over-training.”
