Jay Z wowed the crowd when he made an unannounced stop at Beyoncé's final concert in Brooklyn Monday night.
The rapper stopped by the Mrs. Carter World Tour and jumped onstage right after she sang her latest single, "Bow Down."
Queen Bey let Hov take the reins and watched him perform "Tom Ford" while sitting stage right.
Toward the end of the song, however, Mrs. Carter joined in and gave Jay a big hug after their adorable duet.
The "Grown Woman" singer rocked a jersey for the song with the number 04 on it and "Carter" written across the back. Now that's a stylish shout-out if we've ever seen one!
The couple's famous BFF was also in the building last night. Gwyneth Paltrow stopped by to watch her gal-pal serenade the audience.
Solange Knowles stopped by as well to support her big sister and took to Twitter to give a raving review of the evening.
"My sister literally just wrecked that show," she wrote. "She is simply, the best."
But this isn't the first time these two music industry heavyweights have been on the same stage together in Jay Z's hometown of Brooklyn.
Back when the stadium first opened in October of 2012, Jay performed for eight nights to christen the venue he owned a percentage stake in.
The two performed "Crazy in Love" together among other hits, and Jay even let Bey have her moment to sing some of her own singles.
The rapper became so distracted with his wife's sexy dance moves that he was heard saying on the mic, "Oh sh-t, I should probably rap here." Looks like he almost missed his cue!
Jay famously slapped his girl on the behind without her knowing, causing a shocked Beyoncé to grab him and whisper something in his ear in a cute (and rare) candid moment.
These two sure do know how to balance that spotlight!
