The special guests on Drake's "Summer Sixteen" tour just keep getting bigger and bigger. Following Kanye, Gucci Mane and 2 Chainz, Eminem, and many more, Wednesday night's show at Miami's AmericanAirlines Arena brought one (or, rather, two) of the most intense surprises yet. Lil Wayne and Rihanna joined Drizzy for unannounced guest appearances, driving the Florida crowd wild.

Wayne appeared first, with RiRi following within minutes. Weezy performed "A Milli," of course.

He also had a quick message for Cash Money before exiting the stage.

Rihanna then had a mini-set, performing with Drake on "Work" and taking a solo turn on "Bitch Better Have My Money."

The on-and-off (and maybe now on again) couple embraced and kissed onstage.

This was the second night of a two-night stand in Miami, and folks who had tickets for night one were more than a little disappointed at missing out.

Those who were there, though, were understandably ecstatic.

The "Summer Sixteen" tour continues on Friday night in New Orleans.
