It has been reported by visitors of Nadine Coyle's Irish themed LA bar, that Coyle herself named ex band mate Cheryl Cole a "talentless bint."
She was apparently "stone cold sober" when she made the claim.
The singer had walked to the stage to knock out a couple of songs from her flop of an album 'Insatiable,' when she was asked to sing one of Cole's songs instead.
Coyle however did not take this well and yelled; "No way. I'd rather eat a slice of cake, than sing any of that talentless bint's songs."
A huge cheer then took place with the customers. However, one woman, thought to be around 40 years old, threw a potato at Coyle and yelled; "F**k you Irish grasshopper."
Nadine was knocked unconscious from the blow, and was taken to hospital. According to medical experts, she suffered concussion from the blow from the potato.
Dr. Migadinga said; "Nadine will have to take it steady for now. The blow from the potato has really taken its toll on her."
Nadine will return home from hospital on Wednesday.
