Hilary Duff and ex-NHL star Mike Comrie have just announced they've separated…and according to TMZ "it's pretty obvious divorce is just a matter of time."

The couple says they "have mutually decided to an amicable separation" and will "remain best friends and will continue to be in each other's lives." 

Duff and Comrie were married in August of 2010 in Santa Barbara and Hilary gave birth to son, Luca, March 20, 2012. 

Hilary's mother, Susan Duff says that "they're better friends than a married couple."
