The American hitmaker has offered his condolences to Lulu Dikana's family.
The songbird made headlines just two weeks ago when she opened for the RnB hitmaker during the SA leg of his All Of Me Tour.
"So sad to hear of the sudden passing of @LuluDikana, who recently opened for me on the #AllOfMeTourSA. My condolences to her family & fans," John tweeted.
Lulu died in hospital on Wednesday night after suffering from a short illness. Funeral details have not been confirmed by her family yet.
May her soul rest in peace!
