What a treat!
Attendants of Lollapalooza 2014 were in for an awesome surprise this past Friday when they chose to go to Eminem's stage in Grant Park in Chicago.
That's because a certain Rihanna made a special guest appearance at the show, and the crowd LOVED the surprise!
Especially when RiRi took over the vocals for Eminem's infamous song Stan and the two went on to nail their collaboration!
For some reason these two just work SO well together!
Check out the three song that they performed at Lollapalooza
