Calling all Gleeks: We caught up with music legend Olivia Newton-John and got the dish on her Glee debut tonight! “It appealed to me because it’s such a great show about music. I was very flattered to be asked,” she told us. Among other numbers, the Aussie re-lived her ‘80s hit “Physical.” “For our dance routine, they reconstructed the gym as it was when I did it in the ’80s. I’ve never laughed so much! My face was hurting,” she said. But leg warmers and killer vocals aren’t all Newton-John shared with the Glee cast. While on set, the thoughtful star handed out Zamus, her favorite herbal drink from Amazon Herb Company, which was founded by her husband, Amazon John. “The cast loved it,” she said adding, “They are all so gifted and lovely!” Catch Olivia Newton-John’s Glee debut tonight at 10p.m. EST on FOX!
