Credit: Hilary Duff on Twitter Photo: Hilary Duff, Mike Comrie, and Luca on Vacation

Is it just us or didn’t Hilary Duff and hubby Mike Comrie split earlier this year? We’re not saying that two people can’t be friendly after deciding to go their separate ways, but Hilary just shared a photo on Twitter that has us scratching our heads. The photo in question shows the pair and their adorable son Luca together on vacation — with Mike’s arm around Hilary. So are these two back together?

Hilary didn’t caption the photo with much info, but did include three hashtags: #modernfamily #vacation #juicypear. From this we can gather that Luca is eating a juicy pear while on vacation with his parents (a juicy pair), who are a modern family in the sense that they are separated and still maintain a friendship. Geez, who said hashtags weren’t informative?

Back when the two decided to split after months of counseling, a source close to the couple said “no major incident” caused the split, but that the two just started to “drift apart.” The source went on to say that Hilary and Mike worked better as friends and even noted that they are “great friends.”

You may remember back when Hilary stepped out on Grammy weekend all alone. She didn’t bring Mike to the public event, but now they’ve decided to go on a family vacation together? It all sounds innocent, but it’s the fact that Mike has his arm around Hilary that leads us to think that the two are being extra friendly with each other. And let’s not even talk about the fact that Hilary also shared a photo of “Happy Valentine’s Day” written in the sand with a heart drawn beside of it. Those footprints are a little on the bigger side, right? Did Mike write it in the sand for Hilary?

We’ve got our eyes on these two.

Are Hilary and Mike just good friends or do they look like they’re getting a little too friendly? Hit the comments and sound off!
