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 to take her mind off her battle with brain cancer while she had infusions.

High school student Jennah completed her 12 chemotherapy sessions in July, 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.

Mom, dad and siblings Luke and Larkin joined her as doctors and nurses at the at Norton Children’s Cancer Institute in Louisville, Kentucky, cheered.

“I’ve watched all of the seasons of Friends on Netflix," said Jennah.

"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.

The next day doctors performed emergency brain surgery and found that the tumor, known as a germ cell tumor, was cancerous.

Jennah completed chemotherapy and will now start radiotherapy with doctors confident that the cancer has not spread and that she will make a full recovery.

Astonishingly, Jennah even performed as Wendy in a production of Peter Pan at the Louisville Academy of Fine Arts, less than a month after the intense surgery.

“I was cast as Wendy and I performed in slippers. I wasn’t strong enough to go en pointe," she said.

“My best friend was playing Peter Pan and because we were performing with masks on, she could talk to me on stage and she was able to tell me the moves.

“The choreography slipped my mind because I had short term memory loss due to my surgery.”

“I don’t think there was a dry eye in the house," said Jennah's mother Jill.

Jennah has not yet seen the much-hyped Friends reunion special first broadcast in May but her grandmother has taped it for her.

“I haven’t watched it yet, but my grandmother taped it for me so I’ll see it soon,” she said.
