Looking tanned and fit following her stint Down Under, where she was presenting the after-show I'm A Celebrity Get Me Out Of Here! NOW! Laura showed off her enviable midriff in a tight green cropped top.
Laura (26) parted ways with Corona's frontman Danny, who is the son of Mary Black, at the end of last month.
They had been dating since January last year and were living together in London.
But cracks began to appear when Danny failed to fly to Australia to join Laura for a planned reunion.
Blonde beauty Laura has since changed her Facebook status of being 'in a relationship' -- leaving it blank -- and has told close friends they are no longer together.
Speaking before the split, Bray girl Laura said: "He's my best friend and he gets me, I'm a crazy little girl; he gets my lifestyle and gets the things I do.
"He understands me. I'm quirky. I can never sit still for a second," she continued.
But she admitted the pressures of work caused problems: "It's ridiculously hard. But every relationship is hard. Even if we both worked nine-to-five, we'd have troubles."
