The plunging number only just protected the 31-year-old’s modesty but as she walked the red carpet, her ample assets threatened to spill out.
However, the gorgeous brunette – who plays lifeguard Summer Quinn in the film – appeared to be wary of the risk as she placed her hand over her plentiful chest to avoid a shock nip-slip.
The New York-born beauty matched the sexy attire with a pair of lace-up high-heels and kept her accessorises to a minimum as she let her cleavage do the talking.
