It's the American Kate Middleton
Yes, she really is Kate Middleton - Kate Middleton, the Boston bicycle enthusiast, that is.
But that has not stopped the 32-year-old from being confused with the woman who is about to marry Prince William.
Recently, Facebook accused the Boston Middleton of being an impostor and deleted her account. And reporters keep showing up at ATA Cycle, a bicycle shop in Concord, Massachusetts, where she works, and asking her to speak in a British accent.
"I'm really not interested in pretending I'm British," said Ms Middleton, who is originally from Louisville, Kentucky. "And I'm not really interested in pretending I'm the other Kate Middleton so I basically refused on all five requests to speak in a British accent."
The mix-up began in January after Ms Middleton tried to log on to her Facebook account only to find out that the account had been suspended on suspicion of it being fake.
She wrote Facebook an email and said that yes, her name was Kate Middleton, and asked if could she have her account back.
"Facebook disabled my account for using a fake name," she tweeted after the Facebook deletion. "Will the real Kate Middleton please stand up?"
She soon discovered that Facebook has also untagged her in all of her photographs. "Further evidence one doesn't really exist unless they are royalty..." she quickly tweeted. The account was reinstated about a week later.
She was not the only Kate Middleton to face a temporary ban on the popular social media site as the royal wedding in London approaches.
At least three others - an Australian woman and two British women all named Kate Middleton - have been booted off Facebook and were later allowed back only after proving that they really were Kate Middletons.
