There has been no word so far when the singer got his diagnosis or what kind of symptoms he has had experience.

But after Monday's live show, Entertainment Tonight caught up with Perry and Richie asking them of Luke Bryan's current status.

The "Fireworks" hitmaker said, "He's totally good. I think he's gonna be all right."

"I think we'll be seeing him next week."

The 36-year-old mom of Daisy Bloom revealed that Bryan was texting them the entire time.

"He was blowing up our phones during the whole episode. Some of it we can't even say."

71-year-old Richie quipped, "We can't say half of it!"

Additionally, Katy Perry revealed that Luke Bryan agreed with all of the judges' critics during the live episode.

The "Roar" singer explained, "He was just giving critiques at home. I guess, alone in his room."


Paula Abdul on 'American Idol'

Meanwhile, Paula Abdul, who has been a judge on the singing-competition series for the first eight seasons, revealed returning on the show gave her a "nostalgic" feeling.

She told ET, "I didn't have time to think about it because it was literally, I got the call on Friday night and I was worried because I was getting my second vaccine and I thought, 'Oh my God, what if I have a reaction?'"

"I was able to move my appointment to Saturday night, so yesterday I was feeling kind of crappy, but today I woke up fine. And it was fun."

Speaking of how working with Perry and Richie was like, Abdul confessed, "I love being on this panel tonight. It's way different than the panel that I was on, that's for sure."
