Somizi Mhlongo has expressed his disappointment at the guest pastor who shamed gay people at Grace Bible church on Sunday.

In a series of videos, the Idols judge shared on Instagram how he walked out of a church service when a Ghanaian bishop Dag Heward-Mills slammed homosexuality.

"I'm not going to sit there and listen to people offend me, this is who I am! I am a gay man! Get it straight into your skull, my soul is alright with my God. Let me deal with my God, with my soul." said Somizi.

The pastor has become the centre of a social media storm following his homophobic comments.
