Paris Hilton dress trousdale blonde beverly hills Paris Hilton channeled old Hollywood glamour when she donned this long sequined gown for the Race To Erase MS event in Century City last night.

A source tells us Paris' ex Doug Reinhardt was begging Brandon Davis' mom Nancy to get a comped 'celebrity' invite to her charity event. Word has it, he was calling and having his friends call all week trying to get on the list but Paris' BFF Brandon wasn't havin' it. He and his mom said no way! Geez, couldn't the frozen burrito heir at least offer to pay for a ticket to a CHARITY event. What a cheapo!

The gala featured performances by Heart and Avril Lavigne. And after the event, Paris headed to Trousdale with her sister Nicky.

Loves it!
