Serena shares her Top 10 iTunes playlist

Twenty-three Grand Slam titles, four Gold medals, and let's not forget a former No. 1 who's on a quest to hold the top spot once more after having baby Olympia. Serena Williams is an icon on and off the court but what pumps her up, what gets her motivated during workouts and before matches? The star recently shared her Apple Music playlist.

She listens to nine-time Grammy nominated R&B singer Ciara. The two have been close friends for a long time and have the cutest playdates with their daughters.

Kelly Rowland's new single is also in rotation, and like Serena and Ciara, these two go way back. They have been supporting each other for over a decade. Rowland comes out to cheer for Serena whenever she can, and has been spotted in the US Open crowd rooting for her on several occasions.

Both Ciara and Kelly Rowland attended Serena's wedding to Alexis Ohanian.

Overall, Serena's playlist is upbeat and energetic just like her on-court mentality that has taken her to the top.

Serena also listens to an artist who isn't featured on her most updated playlist, you may know her as Beyonce. The two are also friends and Serena made an appearance in "Sorry" which is arguably the most powerful song on Beyonce's 2016 album Lemonade.

The seven-time Wimbledon champion beat Julia Gorges on Saturday for a spot in the second week of Wimbledon.
