What's your opinion on Cheryl Cole?

She's very pretty but seems not to have that much talent. I'm in Australia and I heard about her through her relationship with Ashley Cole and their much publicised break-up. Seems to me she ended up hating the man or it ended very badly but she still keeps his surname to remind her of this and everyone else. Who were Girls Aloud anyway? Sounds like a very processed sugarine taste that says the people involved must be of questionable talent anyway. She shouldn't really be judging in the US if no one has heard of her.
