This is the moment a huge 'Friends' fan celebrated the end of her chemotherapy with a sign that reads ‘The one with no more chemo,' in a nod to the show’s episode titles.

Jennah Blair, 17, watched the hit TV show starring Jennifer Aniston and Matt LeBlanc, to take her mind off her battle with brain cancer while she had infusions.

High school studentJennah completed her 12 chemotherapy sessions this month, and nurses surprised her with the sign that featured the iconic purple door and gold peephole frame from the series.

Jennah held the sign as she rang the bell to mark the end of the grueling treatment.

She was accompanied by her mom Jill, 44, dad Jimmy, 44, her brother Luke, 19, and sister Larkin, 14, as doctors and nurses at the at Norton Children’s Cancer Institute in Louisville, Kentucky, cheered.

Jennah said: “I’ve watched all of the seasons of Friends on Netflix. I watch a couple of episodes a week and I watch it while I’m having infusions done.

“It really helped me to watch something familiar in a place which was really unfamiliar to me.

“The sign made me really happy - it shows how the healthcare workers went the extra mile to make me feel comfortable.”

Jennah, who is training to be a ballerina in Louisville, Kentucky, was diagnosed with a brain tumor in April after she went to the ER with a crippling headache.
