Singer/songwriter Alexa Ray Joel has interviewed her mother, model Christie Brinkley, for the new issue of society magazine Hamptons.
The Notice Me singer and her mum discuss Brinkley's role as Roxie Hart in Chicago - her Broadway debut.
The ageing beauty confesses she took on the musical role to prove to herself she could do something she had always dreamed of.
Brinkley says, "It's not every day that one has an opportunity so rife with possibility, excitement and adventure. It awakened me to the realisation that this is something I had always dreamed of doing but never had the time, or perhaps even the courage, to pursue.
"I didn't know if I had the goods, but I would rather go down in flames than spend the rest of my time wondering, 'What if?'
"So, with a reckless abandonment and a hot pair of Louboutins, I marched into my audition, ready to have some fun. And believe me, after four or five really tough years, I really was ready to have some fun."
Brinkley had just divorced cheating husband Peter Cook and helped Joel's father Billy Joel through his own marriage split from Katie Lee and a subsequent drinking problem when she signed up to play Hart - and she's having a blast.
She explains, "I got to meet and work with Walter Bobbie, the revival's original director, and he gave me wonderful emotional direction and some very helpful technical direction. For example, he suggested that I hand write all my lines in order to open up other neural passageways toward memorising Roxie's lines.
"Also, the show surrounded me with a team of highly knowledgeable and patient professionals such as my conductor Leslie Stifelman, who worked with me on vocals. I'm also lucky enough to get squeezed in, once a week, for lessons with Broadway's most in-demand vocal coach, Joan Lader, who is helping me find ways to keep singing even through this season's record-breaking, history-making, highest pollen count ever."
