What a little heart breaker!

Hilary Duff shared the sweetest snap of her son Luca via Instagram on Monday.

"[heart]melts Mikey gets photo cred for this one ;)," she posted with the cute candid of Luca, referencing her ex, Mike Comrie, as the photographer.  

We love how the former Disney star has been dressing her little guy these days -- how adorable is that blue tank top?!

It definitely seems like Duff and her estranged hubby have maintained a close relationship since announcing their separation earlier this year.

Not only did Mike take the sweet snap of their son, but the exes also spent Valentine's Day together while on vacation with their families.

We're still hoping for a reconciliation -- what do you think of Hilary's latest photo?
