Hilary Duff and Mike Comrie’s split sure is amicable. The former couple, who announced their separation in January, were all smiles as they attended Coachella with some close pals on Friday. A source reveals to E! News that despite going to Coachella together, Duff and Comrie are “still just friends.” Duff and Comrie have remained close and have been spotted out together on numerous occasions with their adorable 2-year-old son Luca. From arriving at the Four Seasons Hotel in Beverly Hills with their baby boy to a hike in the Los Angeles hills, reuniting for a snowy stroll in New York City and now Coachella, these two may exemplify the sweetest breakup in Hollywood history.
