Hilary Duff 'Completely Surprised' by Proposal

Hilary Duff heads back to her car after working out at a private gym on Wednesday (February 24) in West Hollywood.

The 22-year-old actress gave photogs a great shot of her blingin’ engagement ring – gorgeous!

Hil‘s sister Haylie told People that Mike Comrie‘s proposal was unexpected but wonderful for Hilary.

“She was completely surprised,” Haylie said. “I don’t think that happens all the time. I think most of the time people figure it out or have some idea that it’s going to happen, and I think it’s great he was able to do a surprise like that for her.”
