Mika, whose songs like "Mauja hi mauja", "Jugni" and "Tu mera hero" have been chartbusters, announced the news via Instagram on Sunday.
`Hey Nairobi, be ready we are coming together to rock you guys on 18th April,` Mika wrote alongside a video, in which he and the `Baby Doll` hitmaker are seen teasing fans to visit the concert.
This is not the first time that Mika will be performing in Nairobi. The `Jumme ki raat` singer previously headlined a concert there in January 2013.
