If she fell down staircase, the cup may have tumbled all the way down the stairs, but the coffee would have been spilled at the top of the stairs. Was it a plastic mug? Why wasn't the cup shattered to pieces? I still have my suspicions. This Turkish reality star night club owner, her 'pal'? I don't believe him either.
Rich people do not have plastic mugs, methinks.
And if the stairs were carpeted, it could have bounced instead of broken, no?
