"There's always so many opportunities out there, and Venus and I are always trying to expand our brand and do the best that we can do, and if an opportunity presents itself, we would love to see where it can take us," Serena Williams told the Associated Press. "Who knows what's going to happen, but hopefully we'll be able to hopefully continue to expand our brand."
Representatives for the Dolphins are not commenting on the deal.
If the deal closes, Venus and Serena Williams, who both reside in Florida, will not be the only celebrities to own a piece of the Dolphin pie. Musicians Gloria and Emilio Estefan along with Marc Anthony recently invested in the team.
The celebrities are considered to be minority owners, which means they are strategic partners and are not financially necessary, according to new owner Stephen Ross.
Singer Jimmy Buffett has been asked to also become a minority owner but has not yet accepted.
Ross bought the team in January.
