Hilary Duff and ex-husband Mike Comrie are rumored to be back together after being seen almost every day with son Luca but there's no confirmation about the report yet although the singer's sister Haylie said that there is a possibility.

The two announced their separation just this January but their actions speak that they are back in each other's arms.

Hilary Duff and ex-husband Mike Comrie went together with their two-year-old son on a family bonding to LA Kings hockey game last Saturday at the Staples Centre, Los Angeles, the Daily Mail said.

The former Edmonton Oilers hockey player and the "Raise Your Voice" lead star went off with other celebrities to watch their home team battle with the New York Rangers. Also seen enjoying the anticipated icy sport were Chloe Moretz and boyfriend Cameron Fuller, Gene Simmons, Chris Pine and Dean McDermott.

Mike Comrie chose to be laid back in a black trousers and white shirt during the outing while Hilary Duff opted for a rock star vibe as she wore black jeans, leather jacket and grey pullover. Her ensemble was completed with a Chanel bag on one hand and her adorable toddler on the other.

In an interview with People, the blonde's sister, Haylie, said that their family loves Luca's father.

"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," Mark Rosenberg's soon to be wife said.

The sister of the Lizzie McGuire star also shared that Hilary Duff and ex-husband Mike Comrie are "doing great, and they're just taking their time."

"They're young, you know? So they're not putting stress to figure out which way it's going to go."

US Weekly also reported that the 33-year-old Comrie was spotted waiting for his ex-wife in Beverly Hills for Luca's children's music class. A source of US Weekly told that it is the same class where Kim Kardashian and Kanye West's baby North West also attends.

When Mike Comrie is not with the blonde star, reports have it that he's busy training with Harley Pasternak for his chiseled and toned body.
