Top 5 photos: Novak Djokovic's dynamic personality
Five photos in celebration of the No. 1 ranked Serbian star turning 32.
Fifteen-time Grand Slam winner Novak Djokovic rings in his 32nd birthday Wednesday. In celebration, take a trip down memory lane with these five photos of the colorful champion.
1. The 'Djoker' imitated friend Maria Sharapova at the 2008 Australian Open by mimicking her service motion. Look familiar?

2. During a rainy day at the 2014 French Open, Djokovic invited a ball boy to sit down with him during the delay. He even offered to hold the umbrella.

3. Djokovic is back at it again with another impersonation: this time, it’s former coach Boris Becker. In front of Becker and a packed Rod Laver Arena, he gave this hilarious imitation of the German's ball toss in 2014.

4. Up next: disco Djokovic! After his triumph over Denis Istomin at the Rogers Cup in 2013, the Serb gave the Montreal crowd a little victory dance.

5. 2015 Wimbledon winners Serena Williams and Djokovic 'foot fault' the night away at the Wimbledon Champions Ball.
