Serena and Venus Williams to buy part of the Miami Dolphins

Serena and Venus Williams are great on the tennis court, but they've also been very shrewd businesswomen as well. Their latest venture is into the NFL, where they're attempting to buy part of the Miami Dolphins. Looks like the Dolphins will have quite the star-studded ownership, as the Williams sisters will join the likes of Jennifer Lopez, Marc Anthony and Jimmy Buffet.
