Matt Lattanzi (born Matthew Vincent Lattanzi  on February 1, 1959) is an American actor and dancer. He is most commonly recognized as the first husband of singer and actor Olivia Newton-John, and for his acting in films such as My Tutor and the soap opera Paradise Beach.
Lattanzi was born in Portland, Oregon, the son of Jeanette (née Slowikowski) and Charles Paul Lattanzi. His father is a maintenance foreman of Italian descent, while his mother is of Polish ancestry. He was raised in Portland as well, graduating from Benson Polytechnic High School in 1977.
While filming Xanadu, he met Olivia Newton-John, whom he married in 1984. The couple have one daughter, Chloe Rose Lattanzi, born on January 17, 1986. By 1992, Lattanzi's acting career was largely over, and he took a job as a construction worker for a home-building company in California. Lattanzi and Newton-John moved to their ranch in Australia in 1993 so that Lattanzi could audition for the new soap opera, Paradise Beach. He won a six-month contract for the show.
In 2008, he briefly appeared in the MTV reality series Rock the Cradle, supporting his daughter Chloe (a contestant on the show). That same year, Lattanzi—a life-long environmentalist—was reported to be living off the grid near Malibu, California.
His career consists mostly of small movie parts, though he did have a starring role in 1983's My Tutor. Other film credits include Rich and Famous, Grease 2, That's Life!, Roxanne, Catch Me If You Can, and Diving In. Lattanzi also had a significant role in the Australian soap opera, Paradise Beach, and he appeared in four of Newton-John's music videos, Landslide, Soul Kiss, Toughen Up, and Can't We Talk It Over In Bed.
