He may have kept the nation at arm's length for years, but Andy Murray has surrounded himself with a loyal circle of supporters.
Top of the list are his mother Judy and girlfriend of seven years, artist Kim Sears.
The pair share a home together in Surrey and are loving "parents" to Border terriers Rusty and Maggie May.
Miss Sears, 25, is the daughter of former Lawn Tennis Association head of women's tennis Nigel Sears and has been described by Judy Murray as "the best thing to happen to Andy".
She is a regular fixture in the players' box and has become the darling of British tennis, with constant focus on her fashion choices as she supports her beau.
Murray's mother is the other leading lady in his life. Briefly a professional player herself, the 53 year old is now one of the country's top coaches and captain of the Fed Cup team.
She taught both Andy and brother Jamie as juniors and is a staunch supporter of both sons.
Judy may spend her life around tennis, but she hasn't played for years, she has said, telling the Daily Telegraph: "I think because my life is saturated with it.
"I'm still passionate about it, but it's a bit like a busman's holiday for me when it comes to playing. I'd rather do anything else if I had the choice."
Her ex-husband, Andy Murray's father Willie, is another person likely to be in the players' box for his son's big moment.
He is less prominent than Judy and juggles running a chain of newsagents in Scotland with following his son around the world.
Brother Jamie, who departed from the men's doubles and mixed doubles in the first round of this year's tournament, will also be on hand. The pair's rivalry spurred Andy to worldwide success, but his brother will no doubt be rooting for him in today's match.
But absent from his supporters today will be Murray's grandparents - his mother's parents - as his grandmother Shirley recovers from a broken hip.
Judy Murray told the Telegraph: "Mum broke her hip a few weeks ago, so it'll be the first time they've missed the tournament.
"But I know they are there willing them on in spirit,. There's nothing like having family there for support, and like Andy, I wear my heart on my sleeve, so I'm there cheering loudly."
Along with family, the British number one will be backed by "Team Murray".
Leading the way is coach Ivan Lendl, credited with bringing a cool head to the Scot's game.
After a long search for a permanent coach following his split from Miles Maclagan, Murray turned to eight-time grand slam winner Lendl at the start of 2012.
Czech-born Lendl is an imposing sight courtside, showing almost no emotion during Murray's matches.
Jez Green is Murray's fitness coach and widely credited for turning him from a skinny youngster to a bulked-up athlete.
He puts Murray through a punishing fitness regime, often in the baking heat of Miami, and has him on a strict diet that can often include up to 50 pieces of sushi in one meal.
Murray's hitting partner Dani Vallverdu will also be on hand. A former singles player himself - if only ever reaching number 727 in the world - Venezuelan Vallverdu has known Murray since they were both at the Sanchez-Casal Academy as teenagers.
Vallverdu acts as assistant coach to Lendl and is Murray's regular hitting partner.
And last but definitely not least are Louise Irving and Matt Gentry, who take care of Murray's PR.Suggest a correction
