Hilary Duff and Haylie Duff are so close, they're like sisters.
So you know it's a big deal for Hilary's hockey player boyfriend, Mike Comrie, to have officially passed the all-important Haylie test.
"I think he's great and so special," said big sister Haylie Duff, 22, to People at the Guess/Conde Nast Movies Rock party in L.A. on November 29.
"I love him. He's a really great guy."
Hilary Duff and Mike Comrie - the former collegiate All-American and 27-year-old forward for the New York Islanders - have been dating since the summer. That's not too long, but Mike Comrie is already known for big displays of devotion.

In September, Mike Comrie "surprised" Hilary Duff with a $100,000 Mercedes in honor of the singer and actress' 20th birthday.
"He's good to her," Haylie Duff said. "That's all I care about."
A lot better than Jordin Tootoo was to Kellie Pickler.
