Clara McGregor, the oldest daughter of McGregor and his ex-wife Eve Mavrakis, threw some major shade at the actor's girlfriend and "Fargo" co-star, who Mavrakis reportedly believes was dating McGregor during their marriage. After a Winstead fan Instagram account praised the actress as "the most beautiful and talented woman on earth," Clara responded with a not-so-nice comment.
"Most beautiful and talented woman on earth???" Clara wrote. "Oh man y'all are delusional. The girl is a piece of trash :) x [sic]."

McGregor split from Mavrakis last October after 22 years of marriage. The actor filed for divorce from the production designer in January. Mavrakis said that the divorce was "upsetting," but that her children were the priority.
"It's disappointing and upsetting but my main concern is our four children are okay," Mavrakis told The Sun at the time.
Clara isn't the first or only daughter to slam her dad's relationship. Her sister Esther Rose also blasted the relationship in a song. After seeing photos of McGregor and Winstead kissing, she wrote, "Seeing those pictures, they're making me cry."
McGregor and Winstead were last pictured together in April, and that same month he supported her at the New York premiere of her film "All About Nina."
