Still living it up in southern Florida, Stephanie Pratt practiced up on her beach volleyball skills in Miami on Tuesday afternoon (June 30).

Taking to the beach with a few friends, the MTV reality starlet donned a skimpy pink bikini as she displayed her athletic prowess while doing her best to keep her top from falling off.

Keeping active on her Twitter account, as well, Miss Pratt wrote, "So tired! Just went for a swim and played volleyball and soccer in the miami heat!"

As previously reported, Stephanie spent her weekend in the sunshine state enjoying time with friends and checking out a private screening of "Transformers: Revenge of the Fallen".
