Swift joked that the "Bad Romance" singer was responsible for her love luck with Calvin Harris through a Tweet to a fan on Saturday.
The 25-year-old dished out some relationship advice when Swiftie Alex Goldschmidt Tweeted about his struggle to find romance.
"I pride myself on still thinking love can be like a romantic comedy but sometimes I just think I'm behind and just won't catch up," Goldschmidt wrote.
The singer didn't hesitate to respond, and wrote back "Go read Gaga's tweet that she sent me a few months ago. It's good love luck."
"Because it's not a tweet," she added. "It's a magical spell."

The Tweet in question? Gaga's kind words to Swift back in early March.
"@taylorswift13 wow you're a sweetheart! Life is friends, family, and love! We all see that in you, your prince charming will come," the singer, 29, wrote in response to Swift's praise of the pop star's Oscars performance.

The "Alejandro" singer also weighed in on Saturday, responding to Swift's claims of love sorcery.
"@taylorswift13 I only cast happy spells! Unless there's bad blood," she wrote. "I have a separate cauldron for that. Happy for u."
