Susan Boyle has written a letter of apology to airline staff following a row at London's Heathrow Airport on Monday. The 55-year-old singer had to be escorted out of the British Airways lounge after becoming involved in an argument with a member of staff ahead of her flight home to Glasgow, and has now written a note to apologise personally for the incident, the Mirror reports.
Following the incident, a spokesperson for the former Britain's Got Talent star said her behaviour was characteristic of Asperger Syndrome, which Susan was diagnosed with in 2013.

Susan Boyle has apologised for her outburst at the airport
"The incident at Heathrow occurred because of Susan's well-documented Asperger Syndrome. It is a lifelong condition and one of the many characteristics is outbursts," the representative said.
"She continues to enjoy her music career. That is very important to her and brings happiness to her life whilst trying to balance the many challenges that Asperger's brings."
Susan has previously spoken of her relief following her diagnosis three years ago, and finally receiving a medical explanation for the "acute anxiety" and "emotional outbursts" that have inflicted her throughout her life.
The star will start recording her seventh album this year
Asperger's is a form of autism which typically means a person struggles with their emotions and has difficulty in social situations.
"It's a very difficult subject to talk about because you always feel that eyes are on you, and people view you as different," Susan said in a 2014 interview.
"I like to see myself as someone with a problem, but one I can solve. It is definitely getting better."
The singer certainly has plenty to look forward to in the next 12 months, including the release of her new album. A source close to the star said that Susan has got "lots of great things planned for this year and will start recording her seventh album next month.
"She's in a great place, with people who love and care about her looking out for her back home."
