Our hearts are melting. Could Taylor Swift be any sweeter?

On Monday night, Swift, 25, FaceTimed with Jalene Salinas, a 4-year-old fan from Texas dying of terminal brain cancer. Her last wish was to dance to Swift's "Shake It Off," and Swift made it happen.

Salinas' mother launched a social media campaign to grant her daughter the wish, using the hashtag #ShakeItOffJalene, and it went viral.

Swift, while in London for the Brit Awards last week, noticed and she vowed to reach out to the young girl.

She spent about 20 minutes on FaceTime with her young fan, and the video footage couldn't be more heartwarming.

"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,'" Swift said on their FaceTime chat. "You look beautiful tonight, you really do."

In a YouTube video after the call, Jalene thanked supporters for helping make her wish come true.

We're seriously still drying our tears. Tay, we love you.
