The Houston Rockets are currently for sale, and rumor has it that Beyoncé is interested.
The team is valued at over $2 billion, so she'd probably just be making a minority investment as part of a larger ownership group. She hasn't commented on this at all, but she IS a pretty big basketball fan. She and hubby, Jay-Z, are often seen court side at Knicks games..and the Rockets would be perfect because he hails from Houston.
