While Niall Horan did not disclose any information about his illness, an unnamed source who was on the same flight told MailOnline:

"He seemed fine when boarding and early on in the flight, but later on had wet, cold towels around his head and neck. On final descent he was vomiting quite violently."

The source also acknowledged that the British Airways crew truly did all they could to help Horan, saying:

"The crew were indeed superb, could not have done any more for him, and called ahead for BA Special Services to meet him on the plane and escort him through the border and to baggage reclaim."

The source also noted that, despite being sick, Horan was very 'polite and welcoming' as he signed the source an autograph. They told the outlet:

"He actually very kindly signed an autograph for me to give to a friend whilst we were waiting for our bags, and could not have been more polite and welcoming. He seemed a little bit better at baggage reclaim."

Horan was flying from LAX to London ahead of his appearance on RTE's Late Late Show on Friday.

On Friday, the official Twitter page of The Late Late Show announced that Horan, who is 'very poorly,' would not be able to make it to the show. Thousands of Horan's fans took to social media to wish him a fast recovery following his tweet.

The news comes almost a month after the singer-songwriter was photographed holidaying in Mexico with his girlfriend Amelia Woolley, whom he reportedly started dating in July 2020. Horan was last spotted enjoying the 2022 Super Bowl game in Los Angeles last weekend.
