After slamming rumors she’s had extensive plastic surgery as “100 percent false,” Alexa Ray Joel brought the house down at Café Carlyle Friday night.

The daughter of Billy Joel and Christie Brinkley has been playing a two-week run at the Upper East Side venue.

Spies saw Brinkley beaming and shooting video in the audience as Alexa belted out the rock classic “A Whiter Shade of Pale” and 1930s tune “On the Sunny Side of the Street.”

“If you don’t know this one, you’ve been living under a rock,” she said before performing her dad’s “Just the Way You Are” at the piano for a crowd including Brinkley’s guests Minnie Driver, manager Jason Weinberg, Andrew Saffir and Daniel Benedict, and pal Mindy Moak.

Alexa plays through April 12.
