With an NBA title already under his belt, LeBron James may be ready to conquer the final frontier... wedded bliss.

TMZ has unearthed what appears to be LeBron's "Save The Date" for his upcoming nuptials to longtime girlfriend Savannah Brinson.

But LeBron being LeBron, the invite isn't for a single day, but for an entire wedding weekend. The "Save The Date," with the Heat star, Brinson and their two children dressed in formal attire, says the festivities will take place September 13-15 in San Diego.

After putting up the game-winner in Wednesday night's Heat win over Orlando, LeBron and his teammates will be back at practice on Thursday where the focus may be on "I Do's" instead of dunks.
