*Kelis showed her nipple to the world when she taped for “The Alan Titchmarsh Show” in the  U.K. last week.

It wasn’t on purpose though. Her already low cut top didn’t like where it was and exposed the singer’s nipple.

Embarrassing. Fortunately it wasn’t live and the producers were able to cut some shots out of the show.

A source tells Britain’s Daily Mirror:

“Kelis was performing new single Scream and towards the end her nipple slightly popped out. They had to edit it out. Alan certainly seemed a little hot under the collar afterwards when they were chatting.”

In the mean time, “Milkshake” singer is promoting her appropriately titled album, “Flesh Tone.”
