Tickets for the tour can be found at the Live Nation’s website.

Rihanna and Eminem have teamed up before for the 2010 song "Love the Way You Lie." About working with Rihanna again Eminem said, “Not necessarily a sequel, as much as it is a revisitation. To me, it's more about the vice, and it's more about the nostalgia."

People spotted the Barbadian bombshell partying in New York City popular VIP Room.

A source said that Rihanna was enjoying herself as she was dancing with her friends around 3 a.m.

"She was having a great time. She sang along to a few songs and drank Coronas,” said the source.

Rihanna was dressed in a crop top, ripped jeans and an oversize Chicago Bulls jacket. The source went on to reveal, "She was pretty low-key and stuck to her group of friends.”

Below is Eminem’s single “Monster” that features Rihanna.
