Former Miss World Rosanna Davison has opened her heart about the bitchiness she endures from other Irish women.

The model has revealed that the reason she often prefers chewing the fat with her male friends is because they tend to be less frosty towards her than the fairer sex.

Rosanna, who is singer Chris De Burgh’s daughter, has admitted that reactions to her definitely changed after she won the coveted crown back in 2003.

Even six years on, The Dublin girl still encounters women who react differently to her.

“Sometimes women can be a little bit funny with me and I found that when I went back to college the year after the Miss World thing. I was very lucky in that I had my tight-knit group of close friends there, but I did find that women who have previously chatted away to me in the toilets when they knew nothing about me, wouldn’t come up to me so easily.”

She added: “Even now I still feel it’s easier for me to talk to men than to women, because women are less predictable than men.

“I don’t want to generalise, it’s just my personal experience.”

The beauty queen went on to say that, occasionally, she does get people trying to have a go at her because of who she — or her even more famous father — is.

“I don’t dwell on them. More often than not, it’s at two in the morning and there’s someone singing Lady in Red in my ear, but I take it in a goodhumoured way. I don’t pay attention,” she said.

However, speaking in an interview on 2FM, she hit out at some other celebrities’ ostentatious behaviour, especially given the current economic doom and gloom.

“It would be in poor taste now to be seen falling out of a nightclub with a bottle of champers in your hand. I would certainly never go in that direction.”

The UCD graduate, who got a first-class honours degree and was offered a PhD scholarship, said how it was that “silly stereotype” that all models were dumb that inspired her to push herself.

“It was those kind of stereotypes that spurred me on academically and made me want to achieve everything I wanted,” she added.

And even though Rosanna was pictured sporting a giant sparkler on her finger last week, setting off rumours that she and boyfriend Wes Quirke could be swapping vows, she ruled out giving up her whirlwind life to settle down.

“Certainly not at the moment – that freaks me out!” she laughed. She revealed that she now hopes to branch out into TV and do some more writing in the future.

“I have lots of different plans,” she added.
