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.
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.
Almost immediately, she received numerous tweets urging her to hide the number, although others asked if they could add her on messaging app, WhatsApp.
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.
Bene….ho fatto anche questo….grazie a tutti per i messaggi di incoraggiamento e complimenti….ma ovviamente ora ho cambiato numero 😂😂😂
