Lady Gaga on the phone @ Ellen

Lady Gaga is snowed in her apartment in New York City, but that didn’t stop her from picking up the phone to wish friend Ellen DeGeneres a happy birthday. The pop queen surprised the hostess during her show today, serenading her with “Happy Birthday” and fielding a few questions.

Gaga confirmed that she will perform her new single “Born This Way” at next month’s Grammys, wishes that her album would come out sooner. “Born This Way is coming out May 23. I wish it was coming out in March!” she exclaimed. “I really want to take the time to set it up properly and do all the TV [stuff], like ‘Ellen,’ for example.”

She also took the opportunity to shoot down rumors that she was getting married. “I’m not engaged, that’s so ridiculous!” she giggled.
