Hilary Duff and Ex Mike Comrie 'Doing Great,' Says Her Sister

June 3, 2014 -- Hilary Duff and Mike Comrie announced earlier this year that they had separated.

However, Duff's older sister Haylie echoed what she'd said last month: There's a chance that they might get back together.

"I think they're doing great, and they're just taking their time," she told E! News. "They're young, you know? So they're not putting stress to figure out which way it's going to go."

Duff, 29, added that her family is still very close with her sister's hockey player ex.

"You know, I think maybe we all think it's a lot weirder than it really is, but we love Mike, and he's still so much a part of our family," she said. "I might see Mike actually more than I see Hilary, which is weird!"
