And blogs have been abuzz with rumors of a romance (even though a source tells Us Swift, 20, views Mayer, 32, as a "mentor").
Does Swift mind all the speculation?
"I try not to be a complainer, you know?" she told UsMagazine.com at the 13th annual Unforgettable Evening benefit Wednesday in L.A.
Next up for Swift: Sunday's Grammys, where she's up for eight awards.
"I get nervous about everything!" she told Us. "I am just so excited to be nominated for eight Grammys. That is sort of still unfathomable for me. I've never won one Grammy, so please wish me luck. I'm performing too, so hopefully that comes together."
As for her dress?
"I still have to find something to wear!" she told Us. "But I think it'll all come together the day before!"
