People: AGT Judge Heidi Klum Gives a Positive Update on Simon Cowell's Condition

The ongoing season of "America's Got Talent" reality TV show has been ranked the most unpredictable, yet due to the unexpected events plaguing it.

Aside from the show's production being affected by the ongoing COVID-19 pandemic, last-minute changes have been made to this season's judges panel since news of Simon Cowell's biking accident went public.

The famous TV personality recently went under the knife to get a metal rod installed in an operation that reportedly lasted five hours on Saturday evening.

While indisposed, Cowell's role as a judge in the popular TV franchise will be filled in by award-winning singer, Kelly Clarkson. She took to her Twitter page to share news of her appointment as a guest judge, pending the time Cowell returns. Clarkson wrote,

"My friend, Simon Cowell...won't be able to make Tuesday and Wednesday's live shows for AGT, but no worries America, someone far wiser, cooler, and hotter is taking his seat!"

After Tuesday's live show, the first of four quarter-final episodes, veteran judge, Howie Mandel addressed the topic. He stated that Cowell's absence has been felt profoundly and wished him a quick recovery.

Heidi Klum, who was also absent for some audition episodes after taking ill in early spring and was temporarily replaced by Eric Stonestreet, told PEOPLE that she got an update on Cowell's condition the morning of filming.

If he keeps it up, he might be back on the show the following week.

She also revealed that Cowell is already out of bed–a feat the 46-year-old model tags nothing short of incredible since she was worried about him ever walking again. She said,

"We were told he already got up out of the bed, which is just incredible. When we woke up on Sunday morning to the news, you think, Oh my gosh, will he ever walk again."

A source reportedly told PEOPLE on Monday that Cowell was already walking around and is pretty determined to make sure his injury does not "slow down all the things he's got going on."

Klum seemingly stumped by the rate of her co-judge's recovery added that if he keeps it up, he might be back on the show the following week.

Cowell, who has reportedly been quarantining with his family in southern California, allegedly had a fall from his new electric bike on Saturday afternoon while he was testing it in the courtyard at his Malibu house.

AGT's 15th season premiered on May 26 with pre-recorded auditions shot before the ongoing pandemic and online tryouts after production was suspended in Hollywood.
