A former 'Big Brother' contestant tried to convince tourists she was Duchess Catherine.

Lisa Appleton - who, at 48, is 14 years older than Prince William's wife - introduced herself to people outside royal residence Buckingham Palace as the duchess, much to the bemusement of visitors from as far away as Dallas, Texas, in video footage shared on the MailOnline.
But while her glamorous appearance may have gone some way towards tricking some of the baffled passers by, Lisa's lack of royal knowledge quickly let her down as she forgot the names of Catherine and William's children, Prince George, three, and Princess Charlotte, 19 months.
Despite Lisa's efforts being shot down outside the palace, she insisted she is frequently mistaken for the glamorous royal, who was known as Kate Middleton before her marriage.
She said: "I actually got stopped by a woman who said, 'Was I Kate?' I was in Chester. In a bar.
"The older generation, like pensioners, do think I am either Catherine Zeta Jones of Kate Middleton."
Lisa got engaged to long-term partner Mario Marconi in the 'Big Brother' house in 2008, but their marriage ended in 2013, and she admitted she hit "rock bottom" when their union collapsed and her fame waned.
She reflected: "I had suicidal thoughts, I hit rock bottom.
"After Big Brother and all the success, I lost it all. I was signing on in Warrington, I was on benefits and I was living on about £30 a week. My marriage was breaking down. I couldn't get any work.
"It was at a time when every knew who I was. I was all over the internet. It was very overwhelming. I had people coming up to me all the time. I even had a stalker who followed me around. I was having a hard time dealing with the fame side of things."
