Olivia starred in a little film musical you may have heard of called Grease. Ring any bells? It only became the highest-grossing movie musical and one of the most successful film soundtracks of all time! No big deal. The film earned her a Golden Globe nomination, the soundtrack spent 12 weeks at No. 1, and the success of the film's songs led her to become the second female ever to have two singles simultaneously in the Billboard Top 5: "Hopelessly Devoted to You" and "Summer Nights." As a recording artist, she has won four Grammy Awards and had five No. 1 hits, including her signature song, "I Honestly Love You." She has had success on the pop, country, and adult contemporary charts. Olivia's first film role following the massive success of Grease was Xanadu, which... well, was not a massive success. Let's just leave it at that! She survived breast cancer in 1992 and became an advocate for health awareness. She is also involved with various charities. She currently lives in Florida with her second husband, John Easterling, and has a daughter, Chloe, from her first marriage.
Random factoid: Xanadu earned a whopping seven Razzie nominations — which are given to the worst films of the year — including a "win" for Worst Director. Hey, a win's a win, right?
