Leave it, Leesh, she's not worth it

Alesha Dixon has told Lily Allen to be quiet:

“I like Lily’s song but I don’t like hearing her putting down other artists - we should all support each other.

“It’s wrong to do it as it misleads the public.”

Apart from the awkward fact that, actually, when you're signed to a major label, you're actually competing with other artists, not supporting them, in what way are the public (that's us) "mislead" when someone says how they really feel about something? And even if we were, what would the problem be?

"Doctor, I keep having bad headaches"
"Ah... have you been mislead by how Keith Allen's daughter really feels about Amy Winehouse?"
"Oh... yes, that's it."
