The 47-year-old former talk show host separated from Evans, 42, on Oct. 9, and filed for divorce a week later, according to court filings in Los Angeles. She is expected to pay Evans spousal support.
Lake, the mom of two boys, Milo, 17, and Owen, 13, told PEOPLE in 2011 that she began dating Evans, a jewelry designer, during the summer of 2010. At the time, she described him as a "normal guy. We met through my best friend. He's a nobody but he's somebody to me. He's everything to me."
The couple got engaged in August of 2011 and eloped on April 8 the following year.
"We just clicked," she told PEOPLE in 2012. "It just feels like he was the right one all along."
