Alexa Ray Joel

Christie Brinkley took to social media to share a rare family photo with her three children - who all have different fathers - last week. In one image, a beaming Christie, 70, was surrounded by son Jack Brinkley-Cook, 28, and daughters Sailor Brinkley Cook, 25, and Alexa Ray Joel, 38.  The family came together for a belated Mother's Day celebration and spent the afternoon making pizza.  

Billy Joel 's latest performance for his longtime-running Madison Square Garden residency turned out to be a family affair of sorts. Not only did the Piano Man hit the stage of 'The World's Most Famous Arena' on Friday, April 26, for the 147th time of his illustrious career, he also got to share the moment with his daughter Alexa Ray Joel by performing together, as reported by Us Weekly. And in a walk down memory lane, the festive evening also saw the New York City native serenade his ex-wife Christie Brinkley during the point in the show when he sang his hit Uptown Girl (1983). While initially written about his relationship with supermodel Elle Macpherson, the song ended up becoming a story about his soon-to-be wife, Brinkley. During the performance, the 1980s original supermodel could be seen swaying and dancing along as her ex-husband belted out the catchy melodies and lyrics, which ended up being shown on the massive, overhead monitor, which elicited and even bigger smile from the Uptown Girl, herself.

Christie Brinkley, 70, turned 70 on Friday. On social media, her children were able to wish her a happy birthday.

Last week, the Vacation actress talked about how she has been able to keep her youthful appearance all these decades after fame peaked in the 1970s. The beauty talked to People, saying she is fine with having a few lines here and there, and also revealing that she has tried Botox in the past but is not keen on doing too much to her face. The magazine also focuses on how to appear fabulous while allowing herself to age naturally. I want to hide those wrinkles.' That's the way I'm approaching aging,' said the former Vogue cover girl. People get older and they overdo it, so they get waxy and - I'm not sure if the word is preserved or something.' I want a little life to show on my face, you know?'
