Boris Becker touched down in Montenegro this week reportedly to attend the wedding of Novak Djokovic and fiancee Jelena Ristic.
The couple are said to be tying the knot at the luxury Sveti Stefan this week following Djokovic's Wimbledon triumph last Sunday.
According to the Daily Mail, Becker, who became the Serbian's coach in December last year, has joined the wedding party.
Djokovic and his other half, who is pregnant with the couple's first child, were said to have originally planned to wed on June 14, but postponed the nuptials in order for the world number one to compete at the All England Club.
