Rihanna & Eminem Do a Duet in L.A.!

Eminem had some help rocking his concert Monday night at the Staples Center in L.A. The rapper was joined onstage by Rihanna and the duo performed their new song, “Love the Way You Lie.”

“I want to bring out a very special guest with me tonight. California, make Rihanna feel at home ya’ll,” Eminem told the screaming crowd at Activision’s E3 preview event.

Travis Barker also joined Eminem and RiRi!

The song is featured on the rapper's latest album Recovery, which features multiple projects with other artists and is earning critical praise.
