Former Wimbledon champion Andy Murray has joined the fathers' club at the top of men's tennis after his wife Kim gave birth to a daughter at the weekend.

Media reports said Kim gave birth to a baby girl. Messages of congratulations flooded in on Twitter.

World No. 2 Murray, 28, joins top-ranked Novak Djokovic, 17-time Grand Slam champion Roger Federer and reigning French Open champion Stanislas Wawrinka, who all juggle top-flight tennis with parental duties.

Federer has fathered two sets of twins.

While Murray has yet to officially announce the birth, his paternal grandmother Ellen Murray was quoted in the Daily Telegraph on Tuesday, saying: "Andy phoned yesterday and said 'congratulations, you're a great granny.' "

Murray, who won Wimbledon in 2013, was beaten by Djokovic in the Australian Open final nine days ago before catching the first flight home.
