British socialite Pippa Middleton felt "embarrassed" by the attention she received for wearing a body-hugging bridesmaid dress on the day her elder sister married Prince William. Kate Middleton became Catherine, Duchess Of Cambridge when she married the British royal in London in 2011, and her younger sibling became a sensation as she escorted her sister down the aisle in front of TV viewers across the globe. Pippa has now given her first TV interview and spoken of the magical wedding which captured the imagination of millions, insisting she had no idea her sister's big day would be such a huge event. She tells America's Today show, "It sounds funny to say, but we saw it, as just a family wedding. And actually, I didn't realise, perhaps, the scale of it until afterwards. We all took on the the roles as any family would." Prince William's sister-in-law also admits she felt embarrassed by the attention her now-famous Alexander McQueen bridesmaid dress received, "It was completely unexpected... I think the plan was not really for it to be a significant dress. Really just to sort of blend in with the (wedding dress) train.. (it was) embarrassing, definitely... it wasn't planned." She adds of the dress, "It's actually still in my wardrobe at home. I haven't worn it since. But I think I'll just keep it there... I think it's the sort of thing that I'm sure I'll bring out if someone wanted to see it or my children one day want to see it. Then I'll show them." Pippa goes on to reveal she has felt "publicly bullied" when she reads stories about herself which are not true, but she is adamant joining the royal family has not affected her relationship with her sister, insisting, "We spend a lot of time together. We still do a lot together as a family. We have a very normal, sisterly relationship. We're very close."
