Celine Dion, 54 'focusing on her health and children' amid her battle with  ... trends now

'Resilient' Celine Dion is 'focusing on her health and children' after being diagnosed with rare neurological condition Stiff Person Syndrome, which causes her muscles to tense uncontrollably.

The 54-year-old singer moved fans to tears as she revealed she had the incurable neurological condition in an Instagram post on Thursday - which has forced her to postpone her European tour.

A source told People on Friday: 'Celine is overwhelmed and moved by the outpouring of love and support from her fans,

'It's been a very difficult time and she has a hard road ahead of her, but she is doing everything she can to get back on stage and see her fans.'

'They have always been there for her. For now, she is focusing on her health and her children. She is the picture of resilience.'

The star is mother to three sons - Rene-Charles, 21, and twins Nelson and Eddy, 12 - whose father is her late husband René Angélil, who died in 2016.

 The condition, which affects one in a million people, ultimately leaves sufferers as 'human statues' as it progressively locks the body into rigid positions, leaving sufferers unable to walk or talk. 

While there is no cure for SPS, there are treatments to slow down the progression, with Celine revealing she is doing all she can to minimize symptoms. 

She penned: 'Hello everyone, I'm sorry it's taken me so long to reach out to you. I miss you all so much and can’t wait to be on stage talking to you in person.

'As you know, I’ve always been an open book and I wasn’t ready to say anything before but I'm ready now.

'I’ve been dealing with problems with my health for a long time, and it has been really difficult for me to face my challenges and to talk about everything that I’ve been going through. 

'Recently, I’ve been diagnosed with a very rare neurological disorder called the stiff person syndrome, which affects one in a million people.  

'While we’re still learning about this rare condition, we now know this is what’s been causing all the spasms I’ve been having.'  

Detailing the impact the condition has had on her, Celine continued: 'Unfortunately, these spasms affect every aspect of my daily life, sometimes causing difficulties when I walk and not allowing me to use my vocal cords to sing the way I'm used to.

'It hurts me to tell you today that this means I won’t be ready to restart my tour in Europe in February. 

'I have a great team of doctors working alongside me to help me get better and my precious children who are supporting me and giving me help.

'I'm working hard with my sports medicine therapist every day to build bac my strength and my ability to perform again but I have to admit it’s been a struggle.

'All I know is singing it’s what I’ve done all my life and its what I love to do the most.

'I miss you so much. I miss seeing all of you being on the stage performing for you.

'I always give 100 percent when I do my show but my condition is now allowing me to give you that right now.

'For me to reach you again, I have no choice but to concentrate on my health at this moment, and I have hope that I'm on the road to recovery.

'This is my focus, and I'm doing everything I can to recuperate.

'I want to thank you so much for your wishes and love and support on my social media. This means a lot to me. 

'Take care of yourselves. Be well. I love you guys so much and I really hope I can see you again real soon.'

Celine then updated fans on her tour dates as she shared a poster of the rescheduled and cancelled concerts. 

The mother-of-three first hinted at her health woes in January when she canceled the North American dates of her Courage world tour from March 9 to April 22.
