Amid rumours of their marriage going through turbulent times, India's tennis ace Sania Mirza received wishes from her cricket-star husband Shoaib Malik on her 36th birthday on Tuesday, with the Pakistani batter asking her to "enjoy the day to the fullest".

Sania, the winner of six doubles Grand Slams titles -- three in women's doubles and an equal number in mixed --has recently been in the news, which suggests the celebrity couple are thinking about splitting.
