The adorable Hilary Duff does some reading up on hockey, a sport played by her boyfriend, Mike Comrie, on a professional level. Oh, the things we'll do for our significant others. It's like JR Rotem reading up on STDs for Lindsay Lohan.
New hockey fans Hilary Duff and sister Haylie Duff puck-er up.
Hilary's older sister dished to People about how she busted the singer and actress boning up (yes, we said boning) on her hockey for Mike Comrie.
"I actually caught her with a copy of the Hockey for Dummies book," Haylie Duff, 22, said at the opening of the Foley+Corinna store in West Hollywood.
Haylie says Hilary Duff and Mike Comrie "adore each other" and says it's actually the long-distance factor that makes things work between them.
"He lives in New York and she lives here, and they really put in a big effort to see each other," said Haylie Duff, who has given the pair her seal of approval.
