Lady Gaga, facing the Howard Stern hot seat Tuesday, was asked about a sizzling rumor circulating the music industry.

Stern asked the “Poker Face” singer, “Someone called in and said that you are now a lover of Taylor Swift’s, that the two of you are making love to one another.”

“I don’t think she would be into that,” Lady Gaga said — but later mentioned, “If she’s into that, she can call me!”

The “Bad Romance” singer said of her pop counterpart, “I’ve met her a few times and I can’t say anything bad about her.”

Gaga, 28, shared an anecdote about how Swift won her over, surprising her in the process.

“I was at the AMAs or something, she and I were sitting next to each other, and she goes, ‘Oh my God, I love Artpop and I love “Applause,” and “Applause” is my favorite song and I was thinking, ‘Yeah this chick is full of sh*t, right?” Gaga said.

Gaga said her opinion turned after her trusted stylist witnessed Swift’s fandom firsthand.

Swift “was doing a photo shoot and he was in there styling her … and he goes, ‘Taylor Swift is in here blasting Artpop so loud, and she is dancing, and she is posing,’ and I said to myself, ‘I like this girl, I know why — because she said the same thing to my face that she did behind my back.’”
