If Amber Rose wants to keep her gravity-defying curves under wraps, then she's going to need a bigger towel.

As the model hit Miami Beach on Monday, her poor little white bath towel had not a hope of covering her up.

Luckily that didn't seem to bother Amber, who was happily showing off her figure in a hard-working baby pink bikini.
