Hilary Duff and Mike Comrie Divorcing

Calling all Gentlemen: Lizzie McGuire is back on the market.

Hilary Duff has split from her husband, former professional hockey star Mike Comrie, after less than four years of marriage, a rep for the actress said Friday. Interestingly enough the pair smiled beamingly just weeks ago, as they enjoyed a New Year’s Eve outing.

Despite the breakup, the former couple plan to co-parent their young son, Luca.

A source close to Duff, 26, told People magazine:

“There was no major incident — no big event between the two of them. They really did drift apart. They have put effort and thought into this decision for a long time. They tried couples therapy, but in the end, they realized at this time, they work better as friends. And they really are great friends…She really does care about him and he really does care about her.”

In October, Hilary praised Comrie as “an amazing father” and recently posted an Instagram pic of the family on vacation at Disneyland.
