If it's true then they must have met during the Australian Open in 2007..
This is part of Patric Mouratoglou's diary from that period.
(Yes ladies and gentlemen,we love some sort of gossip from time to time!!Lol)
"Mandy MINELLA, the 343th-seeded Luxembourg player who is making a comeback following a ruptured knee ligament, is travelling with us. She is the girlfriend of Jo-Wilfried Tsonga. He was granted a Wild Card for the final draw and suggested that Mandy join him, knowing that she could train with us on site. She accepts.
We thus board the plane bound for Melbourne with Aymeric Ferrier, Marcos' manager; Yannick Soria, who will devote himself to Mandy's training; my wife and I."
it says that marcos is mandy's no 1. she says it's hard because they are always far away from eachother, but they know that after the tennis career, they'll have plenty of time for eachother. that's it about everything concerning marcos.
I was surprized to see this, mandy and jo-wilfried had been dating for 6 years or so...
