Urban queens Rihanna and Nicki Minaj will be featured on Lonely Island's upcoming second album, 'Turtleneck & Chain,' which is due for release on May 1.

For those unfamiliar with the brilliant Lonely Island, it is the hilarious and wildly popular brain child of 'Saturday Night Live' digital short funnyman Andy Samberg, which also features his bros Akiya Schaffer and Jorna Taccone. The trio is responsible for the much-loved, Justin Timberlake skit, 'D--k in a Box' and even notched a Grammy nomination with 'I'm on a Boat,' featuring T-Pain.

The trio is upping the guest list ante with 'Turtleneck and Chain.' According to The Boombox, the album will include the songs that featured Minaj and RiRi during their 'SNL' stints; Minaj's 'The Creep' and RiRi's 'Shy Ronnie 2: Ronnie & Clyde' are included on the comedic LP.

Although Minaj has had many collaborations in the past, Rihanna is really racking up the them up lately. She debuted the Britney Spears-assisted remix of 'S&M,' her saucy and often controversial single, yesterday. Also, just last week, she partnered with Sugarland's Jennifer Nettles to perform 'California King Bed' at the ACM Awards.

Who will Rihanna collaborate with next? It is anyone's guess.
