Are these two playing nice for their son? Or are they getting back together? It's anyone's guess!

Hilary Duff and Mike Comrie took their son Luca to brunch on Sunday, and they looked like one big happy family, despite the fact the couple announced they were splitting earlier this year. The singer has been quite candid about the ambiguity of their relationship since announcing their breakup, so a reunion doesn't seem totally out of the question.

"We have a 2-year-old together. We love each other. Obviously it wasn't a rash decision that we made. We really are just trying to figure out how we are the most happy – whether together or apart – and we're doing it as lovingly as possible. We would hang out without Luca; we think it's important to keep a strong relationship no matter if we're married or not married. And we love our son. We both want to fight for happiness," she previously told Health magazine.

The Duffster wasn't wearing her wedding ring on this outing, so don't get too excited about a conscious re-coupling just yet!
