Can someone help me find a movie involving 2 sisters... they are rich.. maybe pop stars and one day they go broke. They have nothing left but their super car... Probably Ferrari. They had to move out of their mansion so they go to their ganny's place in the suburbs... They park their car on the street and throw the keys to some random guys on the road thinking they are valet guys... They obviously are theives and they slip away with the car. The next morning they come back to where they parked the car and ask a random guy where the valet guy whom they gave their car was. And the guy reveals that there was no valet and they lost their car. Fast forward in the movie... Another scene where they are trying to earn for themselves and end up being waiters at a party at a mansion where one of the girl meets her boyfriend... Now ex because he left her after her loss.

This is all I remember from the movie... I know it might not be a lot... But any help is appreciated
