The sweet photograph of Andy Murray's dad, Will, getting down on one knee to propose to Sam Watson on Christmas Eve at their home in Dunblane, Pertshire was published by the British tabloid, MailOnline.

Sam Watson's daughter, 20-year-old Brogan couldn't be happier as she tweeted: "Congratulations to my mum and will on their engagement!!"

In other development, the tennis ace signed a lucrative deal with Under Armour, reported to be worth £15 million.

Andy Murray confirmed the deal when he posted in his website: "I am very honoured and excited to be joining Team Under Armour and to help them tell their story globally. They are committed to providing innovative apparel, accessories, and footwear, with an unmatched focus on training and performance."

According to People magazine, Andy Murray proposed to fiancee Kim Sears, which was confirmed by the tennis star's management company.
