Billy Joel and Christie Brinkley’s daughter Alexa Ray Joel is hard at work launching her music career but her brand new look has led a top doctor to tell RadarOnline.com that they believe the 64-year-old Piano man’s child has undergone several types of plastic surgery to create her new look. When Alexa Ray, 28, took to the stage for a sold-out performance at Café Carlyle in New York City this week she certainly looked different than she has in the past. She admits to having a nose job, but there seems to have been a lot more than that done. UPDATE: 
 
 Alexa Ray took to her Instagram to deny that she’s had anything more than a nose job done and credited her makeup artist for her “visibly-positive alterations.” 
 
 “I would just like to add that all of the continuously-circulating rumors that I have had extensive ‘face-work’ and undergone breast-augmentation surgery is simply and entirely 100% false.
– Alexa Ray Joel was playing a sold-out show at New York's Cafe Carlyle when she collapsed onstage and was rushed to the emergency room Saturday night. By the time the news came out yesterday, Joel was already recovering, and the 28-year-old daughter of Billy Joel and Christie Brinkley says in a statement that she's fine and just feels bad about the show: "I was excited and determined to fulfill my final performance and I really wanted to end my run with a bang, but this was not what I had in mind." Her rep tells People Joel was diagnosed with vasovagal syncope, a condition that causes fainting by blocking bloodflow to the brain. Page Six notes that the condition is typically harmless, and E! reports that Joel will not need treatment. She's passed out at a show once before, when she fainted backstage in 2006. Then, in 2009, she made headlines after a suicidal overdose scare (though she later insisted it was neither a suicide attempt nor an overdose). Most recently, she was in the news earlier this month when the media noticed that she looks quite different nowadays (see a before-and-after comparison here) and rumors of plastic surgery surfaced. But Joel put those to bed, insisting all she's ever had done is a nose job.
