— When Joel dated model Elle Macpherson, he thought she was "so tall, I look like Bubbles the Chimp next to her. I realized this was just not going to work." Also, she was 19 and he was in his 30s.Through a mix-up, both Macpherson and the woman he dated next — Brinkley — ended up in Billy's Central Park West apartment at the same time. Brinkley bowed out and he spent the night with Macpherson. But, Billy thought, "I couldn't help thinking that Frank Sinatra would have made a threesome out of that night."
