Mariah Carey + Lady Gaga = diva domination indeed!

As seen via a hot shot lifted to social media not long ago, #Lambs and #LittleMonsters rejoiced as their powerhouse leaders united for the ultimate selfie moments after Mariah wrapped up a stunning set at the Beacon Theater.

With star siblings Phylicia Rashad and Debbie Allen amongst big names out to support the 5 octave songbird during her holiday-themed trek, we’re keen to see what other familiar faces will pop up in the audience as her short residency at the venue draws nearer to its close.

Until we find out, peep one more of New York’s own Mariah and Gaga below:

How cool would a duet between these two be?
