We're not so sure how to feel about this...
What in the world is going on here?!
While the Duffster and her baby daddy were spotted together at the music festival this past weekend, some attendees are saying their affection towards each other was absent.
Especially when Kellan Lutz came into the picture!
"Hilary’s table was right next to Kellan’s. He came up to say hello to her and they both looked so happy to see each other.
They were leaning in close to talk to each other. She seemed more interested in everyone around her than her husband!"
Ooh la la, we're surprise this didn't spark a public argument between the on-again couple!
The Coachella attendee also said Hilary and Mike weren't very affectionate with each other at their table, saying:
"Hilary and Mike were sitting together at the table, but didn’t pay much attention to each other. They weren’t affectionate at all.
She paid more attention to her friends than him. It was as if they were in two separate groups."
Lizzie McGuire's got some explainin' to do.
