The Argentine's girlfriend Chiara Picone has congratulated Lavezzi’s partner Yanina Screpante on the Napoli striker's move to the French capital via the social networking site
Despite denials from the Parisians' coach Carlo Ancelotti, fellow Argentine and ex-Napoli stiker Roberto Sosa has leaked news of the signing to the press, while Javier Pastore’s girlfriend has also hinted the move has been completed on Twitter.
"Chatting to Lavezzi via text messages, I found out the news I hoped to the end I would not receive: the agreement with Paris Saint-Germain is done," Sosa told Sky Sport Italia.
"The rumours of the last few days were unfortunately true. It will be tough for Napoli to replace him."
Meantime, Pastore's girlfriend Chiara Picone congratulated Lavezzi's partner, Yanina Screpante, on their move to the French capital via the social networking platform.
"I'm happy you are coming to Paris. We're waiting for you and we'll spend some fun times together," she wrote.
Recent reports suggest a deal has been struck of around €27.5m plus performance-related bonuses and the profits from an August friendly match for the 27-year-old.
The Paris club faced stiff competition for the signature of Lavezzi as Inter had also set their sights on the Argentina international, but now seem to have lost out to the Ligue 1 runners-up.
The switch is expected to be finalised once the transfer window officially reopens on June 13.
