Be still our pitter-pattering heart!
The supermodel was called upon to beautify amfAR's 20th Annual Cinema Against AIDS Gala on Thursday, and she performed her duties valiantly in a HAWT strapless white Christian Dior dress and white Louboutin pumps.
We adore the pockets and the cutaway that gives the frock such a buoyant quality!
And then there's Rosie's smize — the fierceness is UNDENIABLE!
Thank you for your services, RHW!
