A video of Harmonize working out at the gym revealed a tattoo of Frida Kajala's face on his right calf, sparking speculation among fans.
The tattoo appears to be a permanent reminder of Harmonize's love for Kajala, who he reconciled with after a nasty breakup last year.
Harmonize had previously tattooed the initial 'K' on his body, but changed it to 'Konde Gang' after the breakup.
However, the singer's efforts to win Kajala back were relentless, with him erecting a Sh500,000 billboard confessing his love for her and gifting her two Range Rovers with her name on the plates.
Harmonize denied claims that his actions were a form of clout chasing, stating that he is simply a man in love who wants his woman back.
After months of efforts, Kajala finally forgave Harmonize and unblocked him on Instagram, saying she had chosen to forgive him.
