Dappy's mum has confessed that seeing her son on Celebrity Big Brother has been "embarrassing" to watch at times.

The rapper has hit the headlines on numerous occasions whilst on the reality TV show, with the N-Dubz man recently sucking Luisa Zissman's nipples. He has also bragged about the size of his manhood and cuddled up to the female housemates.

The Metro reports that mother Zoi Contostavlos has been left somewhat red-faced by some of Dappy's actions, admitting: "There were a couple of bits I have found embarrassing to watch. It was not the best side of him but they have to show every side."

This year's Celebrity Big Brother meanwhile has attracted at least 342 complaints so far as the Channel 5 show turns up its risque factor.
