The Dolphins are adding another dash of celebrity: singer Gloria Estefan and her producer husband Emilio Estefan are buying a "small minority ownership" stake in the team, a source said Monday.

The Grammy Award-winning Estefans will join Dolphins owner Stephen M. Ross to announce the investment officially Thursday at Land Shark Stadium.

Ross, who completed his $1.1 billion purchase of the team and stadium in January, has been seeking minority partners for months. He has also been working to infuse entertainment into the stadium experience for fans.

The source said Emilio Estefan has already been working on original songs to add to the game-day experience. Estefan Enterprises includes the couple's Bongos Cuban Cafe restaurant chain and hotels. <!-- END google ads -->

In a meeting with reporters in April, Ross said he wanted the team's ownership to mirror South Florida. "I want this team to represent what South Florida is all about. It's probably one of the most diverse populated places in country," he said at the time.

"You want that to be a positive, want the team to be reflective of that diversity."

The Dolphins announced the signing of sixth-round pick Andrew Gardner , a 6-foot-6, 310-pound offensive tackle out of Georgia Tech. As reported in the Sun Sentinel Thursday, Gardner signed a four-year deal.

His signing leaves seven of the Dolphins' nine draft picks unsigned. Training camp is expected to open Aug. 1.
