John Barrowman quit his appearance at Geek’d Con to be with his mother in intensive care.
The Doctor Who star, 59, posted a video of himself on X, formerly known as Twitter, in which he told fans he was no longer appearing at the Louisiana convention this weekend, as he would be staying by his elderly mother Marion’s side.
Barrowman, who spent lockdown with his parents at his home in Palm Springs, said: "Hey everybody this is a message to everyone who is heading to Shreveport, Louisiana for GeekdCon.
“Unfortunately, I’m gonna have to cancel this weekend. My mother is still in intensive care, and I feel it’s only appropriate that I’m here with her and my dad and the rest of the family.
"So I hope you understand, again go and have a great time there’s lots of guests coming to have a wonderful Con."
He continued: “Support the LGBTQIA+ community, make some videos to tell my Mum to get better. I would love that and sport those flags and all the rainbow flags and post those videos so I can watch them.
“I’m sorry I was looking forward to coming but unfortunately circumstances mean that I can’t so lots of love to everybody and have a great great time."
He captioned the video: "Due to my mother’s illness I am not going to be able to make it.
“Unfortunately she is still in Intensive Care. As always spread the #lgbtqia+ love and make the con a huge success. Have lots of fun ConFamily. I want to see pictures!
"Hopefully I will be with you next year. Lots of love and thanks for understanding. Jb."
Geek’d Con is an annual fan convention held in Shreveport, Louisiana and is one of the largest Comic book conventions in the state.
Last week the actor, who plays Malcolm Merlyn in The Flash TV series, revealed that Marion had been rushed to hospital on Thursday, and that he would have to pull out of Huntington Comic & Toy Con.
He wrote: “My mother was rushed into the hospital last night and she is not very well. I think it’s only right that I stay with my family at this time.”
He has yet to confirm what illness Marion is dealing with.
