Mike Comrie & Hilary Duff Back Together At Coachella -- Do They Look Separated?

Hilary Duff and Mike Comrie don't look like people that recently separated ... instead, they were hanging together at Coachella this weekend looking every bit the married couple.

Duff and her NHL player hubby announced their separation back in January, but still managed to take a family vacation together over Valentine's Day (see below).

Perhaps this relationship isn't over until the divorce attorney sings.
