The last thing she wanted to do was dance with Taylor Swift.

After weeks of checking off every item on her bucket list, Jalene Salinas, a San Antonio 4-year-old battling an aggressive form of terminal brain cancer had one final wish. She dreamed of dancing with Taylor to her hit song 'Shake It Off'.

And when #ShakeItOffJalene went big on Twitter, it became our collective dream. Monday evening around 6 p.m. it finally came true.

Jalene's mom told Eyewitness News, Taylor Swift chatted with the family for 20 minutes during a surprise call via Facetime.

"I'm so sorry you're having a bad night, I'm so happy to talk to you though and I'm so happy you like Shake It off," Taylor said.

"You look beautiful tonight, you really do. You're just as pretty as your pictures." Taylor's Facetime surprise came just in time.

On Saturday, Jalene's health took a dramatic turn leaving her unable to attend a special benefit to raise funds for her final expenses.

"She woke up not being able to walk, and she's very unstable but she's still responding and she's still able to talk." said Jennifer Arriagas, Jalene's mom."

When San Antonians and people coast-to-coast heard of Jalene's bucket list, people rallied around the brave 4-year-old on Twitter using #ShakeItOffJalene to try and gain Taylor Swift's attention.

The artist told the family she heard of Jalene while on tour in London and planned on reaching out as soon as she made it back to the states.

Jalene was in quite a bit of pain and didn't talk much, but she lit up chatting about her baby brother seen in the YouTube video with her dancing to 'Shake It Off'.

"We have a baby named Josh," said Jalene.

Monday's touching moment was the culmination of thousands of tweets and inspirational messages hoping for Jalene's final wish to come true.

"You completed her wish list, we can check everything off and as her mom it just, it means the world to me that she got to do and see and everything is checked off now. It means so much to me that you reached out to us." said Jennifer.

"Everyone in the car with me is crying right now," said Taylor.

And as Jalene's mom wrapped up an interview with Eyewitness News, the brave 4-year-old offered up two simple words of thanks for all her supporters: "Love y'all".
