From scuba diving to the first text she received after her shock Australian Open win over Serena Williams: We reveal everything you need to know about German tennis star Angelique Kerber

She caused a major upset by beating Serena Williams in the Australian Open final - but just who is Angelique Kerber?

The German, who was relatively unknown outside her home country before Saturday night's clash, has risen to number two in the world thanks to her spectacular win.

She is one of the most well liked players on the tour and has thousands of fans on social media, where she does not shy away from posting fun selfies.

A glance through her Twitter profile, which has more than 168,000 followers, shows her leaping in the streets of Times Square, bike-riding in Paris and scuba diving in the Maldives on the off season.

Kerber celebrated her 28th birthday on the first day of the Melbourne tournament and tweeted pictures of her posing on one of the city's beautiful bridges and getting in some practice.

Her tense match against Williams at the Rod Laver Arena was the German's first Grand Slam final.

But she has been an established top 10 resident since making it to the U.S. Open semi-finals in 2011 when she was the world 91.

Kerber then solidified her place as one of the world's best players by reaching the 2012 Wimbledon semi-finals and winning six career titles.

The left-hander was the first German woman in the final at Melbourne Park since Anke Huber in 1996 and is the first to win the tournament since Steffi Graf in 1994.

Unsurprisingly Graf is her idol and she spent time training with the record-breaking champion at her home in Las Vegas.

In an emotional post-match interview, Kerber said that in the lead-up to the tournament Graf has said she was 'hoping for me and thinking of me'. 

'I think when I check my phone I will have a message from her,' she said.

'One of the things you learn from Steffi because you spend some time around her and practised with her and realised how hard she works, even in retirement, what are the little things she helped you with getting over the line in the tournaments?

'When I met her, she told me to believe in myself, I am in a good way and go for it. She knows that I really am working very hard and she told me some day, the work pays off and tonight, it is really, really like she said, all the work and yes, sweating on practice courts, it comes out and it pays off.'

Born in Bremen, Germany, she grew up in a tennis family and her father was her coach for a long time.

She has previously spoken about how she touched her first racquet when she was just three-years-old. 

The tennis star is now based in in Puszczykowo, Poland, where her maternal grandparents own a tennis facility named Centrum Tenisowe Angie – named after her. 

When asked about who her first phone call would be after she won, she said it would be her grandparents.  

She sent some slight shockwaves around the tennis world in May 2015 when she parted ways with Benjamin Ebrahimzadeh and re-hired her old coach Torben Beltz.

Kerber has also previously revealed that so far tennis is her only love, as there hasn't been any time to have a relationship.

'My great love is tennis – that has always been so,' she has previously said.

'Tennis is the most important thing to me right now, I still have time to find a boyfriend, get married and have children, After all if there is one guy out there waiting for me, then we will find each other eventually, without forcing it.'
