During filming, the music mogul experienced a health problem.
Simon Cowell has long been known for his sharp tongue and biting remarks, so it came as a surprise when the 63-year-old appeared more subdued than normal during season 18 of AGT.
Rather than chiming in as co-stars Heidi Klum, Sofia Vergara, and Howie Mandel discussed tryouts, Simon remained silent – but not for lack of interest.
Simon hasn’t been speaking much during season 18 of AGT owing to a medical concern, which he explained in an interview with USA Today.
