Beyoncé and Nicki Minaj gave their fans a rare treat Friday, when Minaj made a surprise appearance at the Queen Bey concert in Paris and they sang the remixed Beyoncé track, “Flawless,” together, reports the New York Daily News.

This is the second time the two superstars shocked their fans since the unannounced release of their duet in August.

The “Anaconda” singer shared some photos from the epic evening on Instagram.

“The QUEEN, could never thank you enough,” was the caption Beyoncé placed under her selfie of the two.

On her album “Pink Friday,” Minaj had predicted the Paris moment with Bey.

“Deluxe song on Pink FRIDAY called GirlsFallLikeDominoes – last line of the song I said: “IM OUT IN PARIS, mudafuka, WIT BEYONCE!” ~ coincidence? Or… Something else? What? God heard me?,” added Minaj, with a picture of the two on stage.

Beyoncé and husband Jay Z conclude their summer tour, “On The Run” this weekend in the City of Lights. Later this month, the concerts will air in a special on HBO.

Jay Z sparked brand new buzz that Beyoncé, 33, is pregnant with their second child, when he changed lyrics to a song during their last Paris performance Friday, Sept. 12.

The rapper, 44, made the possible announcement while performing his hit song, “Beach Is Better.”

“Cause she pregnant with another one,” rapped Jay Z.

The teaser lyric changes the conversation about the alleged marital woes of the talented couple, including rumors of a possible divorce.

Beyoncé and Jay Z were married in April 2008. Their daughter, Blue Ivy, was born January 2012.

The Jay Z lyric change would not be the first time the musical couple made a personal announcement on stage. At the 2011 MTV Video Music Awards, Queen Bey revealed they were parents-to-be when she rubbed her baby bump on stage after singing “Love on Top.”
