Hilary and Mike attended the Teen Choice Awards. The awards were filmed on Sunday night and aired on Monday. Reading stuff around the internet it seems like a lot of people didn't like Hilary's green dress or her hair. Personally I think she looked pretty good. The Teen Choice Awards are a more casual event so I think Hilary's dress reflected that.
Hilary also got to present an award with LL Cool J.
