Though many people questioned Lindsay Lohan's commitment to the Altitude 360 Haiti fundraiser in London last night, sources at the UK hotspot tell us Lindsay absolutely held up her end of the deal when it came to hosting the party.

Lindsay posed for pictures on the red carpet and then headed inside to mingle with partygoers, and she then took the stage and spoke to the audience, encouraging them to donate to the charity.

Lindsay also recorded this PSA with a pal, and even though her red lipstick is a bit distracting, her heart is certainly in the right place!
