Eminem and Rihanna's upcoming "Monster" tour has already gotten bigger.
Earlier this week the pair officially announced they would team for a brief run of stadiums this summer, with gigs in Pasadena, New York and Detroit.
Due to "overwhelming demand," they've added a second night to their stop at the Rose Bowl, Live Nation announced on Friday.
The upcoming trek is the first time the two collaborators have toured together. But their track record has long been cemented.
Their 2010 smash, "Love the Way You Lie," is one of the biggest hits of both of their careers, and they've smartly followed up the song with a handful of other collaborations.
The "Monster" tour takes its name from their latest collab, which appeared on Eminem's most recent album, last year's "The Marshall Mathers LP 2."
Tickets to the pair of shows, which are set for Aug. 7 and Aug. 8, go on sale March 28, although presales kicked off Friday.
