A very happy Kelly Osbourne walked the “Us Weekly Hot Hollywood Style Issue Event” red carpet with her fiancé model Luke Worrall.

She showed off her trim figure wearing a Jeremy Scott Fall 2010 LBD whilst still sporting that horrible purple hair which ages her like 40 years.

Just in case you were wondering what she was wearing, her dress had a helpful message on the back.
