Taylor Swift And Calvin Harris Have A Surprising Relationship Fairy Godmother

A certain pop goddess' witchcraft seems to be highly effective.

Taylor Swift and Calvin Harris are going strong and they have one person to thank — Lady Gaga.

After Twitter user Alex Goldschmidt shared some deflated feelings about love on Friday (July 17), the singer directed him to check out a tweet that Gaga sent her back in March.

"Go read Gaga's tweet that she sent me a few months ago. It's good love luck. Because it's not a tweet. It's a magical spell," Swift responded.

So, what exactly did Gaga tell Swift that helped her lock down a loving relationship so effectively?

"Life is friends, family, and love! We all see that in you, your prince charming will come!" Gaga wrote, after the "Bad Blood" singer praised her performance at the Oscars. It's not eye of newt and puppy dog tails, but the charm seems to have found its mark.

Gaga saw Swift’s advice to Goldschmidt and responded with a new tweet.

"I only cast happy spells! Unless there's bad blood. I have a separate cauldron for that. Happy for u,” she wrote, with a picture from "The Little Mermaid."

As for Goldschmidt? "I have been given my instructions," he wrote in a caption on Instagram. "I leave my love life in Lady Gaga's magical hands. My Prince Charming will come."
