'A Woman's Worth' singer Alicia, who is expecting her second child with Swizz, performed at the free concert on Saturday as a reward to volunteers who carry out deeds to help end extreme poverty.
Meanwhile Jay, who headlined the concert, had a few surprises up his sleeve as he bought out Beyoncé for two songs. The couple pleased crowds with renditions of 'Holy Grail' and 'Young Forever'.
After the concert, it was time to unwind, and the Deans and the Carters sprawled out across a sofa as they hung out backstage.
Captioning the photo on Instagram, rapper and producer Swizz said: "The Deans & The Carters #LovePower. Great music & great vibes."
Of course, all four are close friends and have been long-time collaborators. Not only has Alicia collaborated with Jay on 'Empire State Of Mind', but Swizz has produced many of Jay's hits over the years. Elsewhere, Bey and Alicia also teamed up for 'Put It In A Love Song' in 2009.
Last week, Bey and Jay wrapped up their 'On The Run' tour in Paris where they unveiled intimate home videos of their relationship and their daughter Blue Ivy's birth.
