Phoebe Buffay finally got her big break Wednesday night!

Actually it was Lisa Kudrow, the actress behind the beloved "Friends" character, who picked up a guitar to perform Buffay's catchiest tune, "Smelly Cat," in front of thousands at Los Angeles' Staples Center.

And she had a little help from Taylor Swift!

OK, a lot of help.

Kudrow was the latest celebrity to hit the stage alongside Swift, who's been performing star-studded duets (and then some) during her sold-out run at the Staples Center over the last week. In fact, Selena Gomez joined her Wednesday night, too.

But it was Kudrow's "Smelly Cat" moment that really made the crowd go wild. After all, it's a classic!
