In 2014, Us confirmed that the couple met while she was a hostess working at Eastwood’s Mission Ranch Hotel and Restaurant in Carmel-by-the-Sea, California. (The Oscar winner was formerly the mayor of the cozy beach town.) The pair remained private about their relationship over the years. However, they have attended several Hollywood events together and made their red carpet debut at the 2015 Academy Awards. Eastwood’s film American Sniper was up for six awards including Best Picture. Sandera continued to accompany Eastwood at events including the premieres of his projects Sully, The Mule, The 15:17 to Paris and Richard Jewell. The actor was married twice before his romance with Sandera. He wed model Maggie Johnson in 1953 and the pair share two children, son Kyle and daughter Allison. The exes divorced in 1984.

He shares daughter Francesca with ex Frances Fisher. "I'm a much better father now than when I was younger because then I was working all around the world and I was desperate to find the brass ring, so I worked constantly,” the actor said of his family dynamic in a 2008 interview with The Star. “Now my daughter takes precedence over everything and even though I’ve done a lot of work in the past year, it’s not because I’ve ignored her or not been involved in her school activities.”
