Specifically the relationship with her estranged husband Mike Comrie.
"I'm separated from my husband right now, which has been a very difficult thing to go through, but we have a lot of love for each other and we have this beautiful baby."
It's weird to see Lizzie McGuire dealing with heavy stuff, since Hil's made a career out of being light-hearted and fun — but we absolutely feel for her!
The singer added that there's even a song on her upcoming album about the split:
"[The song is] about my separation and my love for this person, that maybe we're not meant to be together, or maybe we are. It's very, very personal."
Wowza!! So honest!
From paparazzi pictures, it looks like Hilary and her separated man are fine, since they're seen together on the reg…
But we have no idea what goes on behind closed doors!
Hopefully the revealing song will help us understand this cute couple a bit more!
We just want the songstress and their son Luca to be happy!
