ROME: Italian former Olympic swimming champion Federica Pellegrini accidentally left her address and mobile phone number for all to see when she posted a photograph on Twitter on Friday (Saturday in Manila). The 27-year-old Pellegrini, whose Twitter account @mafaldina88 has 455,000 followers, tweeted on Friday morning that she had been subjected to a random doping test and posted a photo of documents relating to the control. The slight problem was that her number and address were clearly visible on the documents. After a few hours, Pellegrini deleted the tweet and added a new message. “Good. I have done it..thank-you for your messages of encouragement and congratulations. But obviously I have now changed my number,” she wrote. Pellegrini still hadn’t deleted the tweet by Friday afternoon.
