Mirra Andreeva is playing the Porsche Tennis Grand Prix also known as the Stuttgart Open which just so happens to fall on the birthday of her coach, Conchita Martinez.
After her latest win in pursuit of her Porsche, it wasn't hilariously saying about the fact she will drive without a license and risk legal trouble if she wins the title but instead it is embarrassing her coach hilariously with a happy birthday song again.
She was saying after her win that she wanted to continue the tradition and she duly obliged.
“Last year I also played here on her birthday and we sang a song for her. I wanna keep the tradition going. Can you help me sing happy birthday for my coach?," said Andreeva hilariously.
She was then asked if she wanted to start and grabbed the microphone and started it off as Martinez started smiling in the stands.
She saw off Alycia Parks in a straight sets win 7-6, 6-3 and will now face off against Iga Swiatek in the Quarter-Finals. Andreeva had seen off Ostapenko in the opening round in three sets.
Andreeva is well known for only giving herself plaudits on the court but in a hilarious way and leaving her coach out of it and they have long been a great partnership as she sails up the rankings.
