Grand Slam-queen Serena Williams turns 34!

New Delhi: Tennis ace Serena Williams entered a new leaf of her life as she turned 34 years on Saturday. The Grand Slam queen who has 21 singles titles to her name, will hope to overcome former Open era champion Stefi Graf's record (22) and all-time tally of Margaret Court (24).

Serena's success has come consistently over her career with a lot of sheer determination and hard work. With the season ending WTA Finals to be played in November, Serena will hope she ends the year with another feather to her cap.

The tennis sensation won three major titles this year and missed out on the US Open to complete a calendar Slam.

Serena has won a total of 34 Grand Slams including doubles (13) and she has been a driving force for many tennis stars.

The birthday girl posted a tweet on social micro-blogging site, Twitter saying a goodbye to 33!
