Hollywood Family Flashbacks

Miley and Billy Ray! Allison and Brian! These famous kids learned from the best

CHRISTIE BRINKLEY, BILLY & ALEXA RAY JOEL

In 1988, a pigtailed Alexa Ray was the perfect combination of her famous parents. Born with music in her blood, it's only logical that she's followed in her dad's footsteps. While Billy performs a residency at N.Y.C.'s Madison Square Garden (where supportive ex-wife Brinkley has popped up in the front row), Alexa, now 28, also has a jazzy Big Apple gig lined up at Café Carlyle in 2015 – Mom is her biggest fan.
