What a bunch of hotties!

As if Miami Beach wasn't already sizzling enough, Mercedes-Benz Fashion Week Swim 2012 is currently in full swing there. And with temps reaching 90 degrees and higher, looking hot while staying cool can be quite the challenge. But these stars prove that with the right outfit, hair, and makeup, the sweltering heat isn't an issue.

Jessica Szohr stepped out at the Raleigh Hotel in Miami Beach on July 14 in a sleeveless blue romper by Sparkle & Fade and tan and black ankle-strap Isabel Marant heels. Besides keeping cool in the breezy one-piece, the Gossip Girl star, 26, also beat the heat with a playful ponytail.

Also at the Raleigh, Kristin Cavallari rocked a bright tangerine sleeveless dress by Jessica Barkley and nude Sergio Rossi Peeptoe Platform Leather Slingbacks. That evening, the 24-year-old Hills alum flaunted her beach-ready body and worked a cobalt blue glass bikini on the Diesel runway to celebrate the event's opening night.

Over the weekend, both Shenae Grimes and Whitney Port stepped out for the Skintimate Studios Ready for Everything Event at W Hotel on Saturday.

Port, 26, wore a navy blue frock with ruffled detail on the skirt and ivory heels while Grimes, 21, opted for head-to-toe black and a patterned overcoat.
