OMG, could these two be any cuter?! A positively ageless Christie Brinkley stepped out to support her daughter Alexa Ray Joel at the budding singer's performance at The Carlyle Hotel on Wednesday, Oct. 21. And it was obvious that Joel could not have been more thrilled to have her gorgeous mama on the scene!

PHOTOS: Stars and their look-alike kids!

Backstage at the famed NYC hotel, the blonde and brunette beauties posed for pics, hamming it up while holding hands and smooching each other's cheeks.

Flashing her classic, mega-watt smile, the '80s icon, 61, modeled a little black dress that flaunted her toned gams, teamed with a leather moto jacket, a crossbody bag, and sizzling lace-up pumps. She finished her getup with loose waves, blushed cheeks, and a rose-hued lip.

Meanwhile, her daughter with ex Billy Joel, 29, modeled a gray, printed maxi dress, accessorized with a corset-style statement belt and her own pair of lace-up heels. She added voluminous curls, plus a metallic smoky eye.

The next morning, Brinkley shared a snap of Alexa Ray belting it out onstage. The proud mom captioned the shot, "Hands Down the best show uptown! @alexarayjoel @thecarlylehotel #nyc #cafecalyle."
