Frankie Valli, 90, leaves fans concerned as he struggles to lip-synch at concert — but rep says he’s ‘just fine’

Frankie Valli’s fans are expressing concern for the 90-year-old’s health after he appeared weak and struggled to lip-synch at a recent concert, but a rep for Valli exclusively tells The Post he’s “just fine.”A video of the legendary singer’s difficult-to-watch performance has already been viewed more than 4.1 million times.

Taken at Valli’s August 3 gig at the Mountain Winery in the San Jose suburb of Saratoga, the video shows the singer looking frail as he fights to climb a short flight of stairs to the stage and grips a handrail as he does.

Valli gets a warm welcome from the crowd, whom he pauses to acknowledge before finally making it to the stage. As his set gets underway, the crooner appears to be lip-synching to his 1978 hit “Grease,” which was also the movie’s opening credits track, but seems to struggle to mouth the words.

As the music continues, the “Can’t Keep My Eyes Off Of You” singer snaps his fingers slowly, holding a mike somewhat unsteadily while flanked by backup vocalists.However, a rep for Valli told The Post on Tuesday: “Frankie is doing just fine and super happy to still be performing.
