'Bad Romance' singer Gaga celebrated her birthday on Friday, and although she received plenty of gifts and surprises, it was a visit from Taylor that really made her day.
In a black and white photo posted to Twitter, Gaga was all smiles as Chicago Fire actor Taylor leaned in to give her a kiss on the cheek.
Captioning the photo, Gaga said: "Another amazing birthday moment. I love surprises!"
Gaga was also thrilled to have been presented with lavish gifts from Donatella Versace. Lucky girl! Gaga's birthday marked the same day that she kicked off a seven-day residency at New York City's legendary Roseland Ballroom.
Taking to Twitter, she said: "Thank you so much for all my beautiful birthday wishes. I feel like luckiest girl in the world this birthday."
The popstar then continued her birthday celebrations over the weekend with actor James Franco, watching him perform Of Mice and Men in Broadway.
Gaga, who has been dating Taylor since 2011, recently opened up about the couple's relationship on Sirius XM's Morning Mash up radio show in New York.
"He's totally in charge," she said. "I mean, when I am home, I am like, shoes are off, I'm making him dinner. He has a job, too, and he is really busy.
"I'm in charge all day long, the last thing I want to do is tell him what to do ... It's not good for relationships to tell men what to do."
