Andy Murray is celebrating becoming a father for the first time after his wife Kim Sears gave birth to a girl.

The British No. 1 welcomed his daughter into the world on Sunday, a representative of the tennis star confirmed to ESPN.

Murray and Sears were married in his hometown of Dunblane last April and announced the pregnancy in the summer.

In the build-up to last month's Australian Open, Murray revealed he would be prepared to fly home early if his wife went into an early labour -- even if that meant missing the final.

The 28-year-old eventually finished runner-up to Novak Djokovic at Melbourne Park, but insisted his family was a "priority" and more important than any tennis match.

Murray's mother, Great Britain's Fed Cup captain Judy, was understandably delighted, writing on Twitter:

Murray's grandmother, Shirley Erskine, also struggled to hide her happiness at the arrival.

"I am absolutely delighted, as you can imagine," she told BBC Sport. "It seems a long time that we've been waiting for this but all's well now as far as I know. I don't have any details I just know that I've got a great granddaugher so that is just lovely.

"All I could think of after Andy had finished playing his final [in the Australian Open] was 'Oh good, at least he'll get home now'.

"It's not easy getting home from Australia. He couldn't have been further away. Fortunately, he was home in plenty of time and all's well."
