Singing legend Tony Bennett is proving it's never too late to fall in love by getting engaged to his long-term girlfriend SUSAN CROW. The 80-year-old star is planning a third trip down the aisle after failed marriages to Patricia Beech and Sandra Grant. A friend of the crooner tells British newspaper The Daily Telegraph, "He's just popped the question to his girlfriend. "He was really excited about it. She's 20 years younger than him and they've been together for 18 years, but he feels like this is the one thing he really wants to do while there's still time." His spokesman adds, "He's old school, so he doesn't want to talk about it. But they've very happy and very much in love."
