John Legend and Alicia Keys

Alicia Keys and John Legend have long been considered two sides of the same coin, and they showcased their chemistry at the O2 Arena in London last evening. Performing during the former’s Set the World on Fire Tour, the pair sang a special duet of Legend’s signature song, “Ordinary People”.

Here is a nifty fact: Legend sang background vocals to Keys’ hit song “You Don’t Know My Name” from The Diary of Alicia Keys album. So, the duo have a long history together and that explains why this latest collaboration seemed so natural. Watch the perform “Ordinary People” below:
