Ke$ha had a Twitter slip up that revealed a surprise Nicki Minaj had in store for fans. The spunky pop star will appear on a remix of Minaj’s “Super Bass,” which will be released on a deluxe edition of the rapper’s Pink Friday album. 

According to Digital Spy, Ke$h spilled the beans in a keyed-up tweet.

“Just saw @NickiMinaj superrr bassssss vid bahaahahaaha AMAZING!! can’t wait for you to hear the remix we [did]. (sic),” she tweeted.

The message was quickly deleted moments later. 

Despite Nicki recently expressing a desire to limit the number of collaborations she works on in the coming future, both her and Ke$ha appear on a remix of the Britney Spears single “Till the World Ends.”
