AceShowbiz - Girls Aloud star Kimberley Walsh has criticized Elizabeth Hurley and Shane Warne for publicly flirting on Twitter.com prior to their romance - insisting it was unfair on their former partners. "Austin Powers" star Hurley met cricket ace Warne earlier this year and struck up a friendly relationship, posting messages on the microblogging website revealing he's her "favorite Australian" and suggestively saying her dog "sends you a special lick and says he'd like to put his silky head on your shoulder".

This month, Britain's News of the World revealed Hurley had spent two nights with Warne at a London hotel, and she subsequently announced she parted from her husband Arun Nayar "a few months ago" after almost four years of marriage. Warne also announced he has split from wife Simone Callahan, the mother of his three children.

British singer Walsh admits she was shocked by the outlandish messages Hurley and Warne were sending each other prior to the scandal - because she'd never want such personal matters made public. In her weekly column for Britain's OK! magazine, she writes, "Flirty Tweets between Elizabeth Hurley and Shane Warne have been published in the papers. I really have no idea why you'd Tweet something that can be read by others instead of texting them!"

"Why do you want the whole world to know things that should be kept between the two of you? It must be hard for their former partners, because no matter what the situation, you don't want to know things like that."
