THIS former US Open champion looks totally unrecognisable with her dramatic new appearance.
And some fans reckon another ex-winner has fallen head over heels for his glamorous compatriot.
This is a former US Open champion[/caption] The glamorous Argentine, left, turned 54 in May[/caption] She cuts a very different look to when she graced the tennis courts[/caption]The tennis superstar captured the hearts in New York with her solo Grand Slam victory all the way back in 1990.
She beat Steffi Graf in a straight-sets final to secure her status in the sport’s folklore forever.
But the ace sports a very different look these days – with the famous curly hair changed up for a stunning wavy look.
The Argentine has taken to Instagram with a series of recent snaps showing off her gorgeous look in plenty of iconic places – including the Colosseum, Wimbledon, the River Plate stadium and New York City.
She also beamed alongside pal Gisela Dulko on the beach in a snap that had adoring fans in awe.
Many followers flooded the comments section with heart-eyes emojis.
Others labelled the US Open champion “fabulous”, “a cutie”, “beautiful” and “sexy”.
But can you work out who the mystery player is?

It is none other than Gabriela Sabatini.
And the fellow Argentine she is being romantically linked with is Juan Martin Del Potro.
PLENTY of tennis stars have stayed involved in the sport since retiring.
But others pursued very different careers. Here are some of the best…
Delpo won his US Open in 2009 and is more than 18 years younger than Sabatini.
However, the keen cyclist has uploaded various pics of the pair together, including one appearing to show them out for dinner in what looks very much like a date.
Gabriela – who briefly dated Donald Trump – captioned the dinner post: “For more moments like these, I admire you and I love you so much!” followed by a red heart emoji.
Sabatini no doubt made sure she smelled extra sweet for her evening with Del Potro, especially because she has her own line of perfumes.
She launched her first colognes during her tennis career in the late 1980s, with her debut signature scent in 1989, and has continued dabbling in the industry since retiring in 1996.
The former world No3 – who earned £6.7million on the court and reached the Wimbledon final in 1991 – boasts legendary status in her homeland.
She even has a statue in Buenos Aires alongside busts of Lionel Messi and Diego Maradona – as well as an orange rose named after her.
Sabatini’s connections to Messi don’t stop there, either.
That is because her niece Oriana Sabatini is a famous singer and actress in Argentina – and she is married to Messi’s Argentina team-mate Paulo Dybala.
