Prior to Wimbledon, two of the biggest stars in tennis spent some time at a Taylor Swift concert in London.
Serena Williams and Caroline Wozniacki were among the celebrities at Swift's Hyde Park show on Saturday. It was only fitting that Williams got to rock the runway when the star singer belted out her hit song "Style."
For Williams and Wozniacki, it was just something that best friends do together:
Williams will begin her quest for a sixth Wimbledon title on Monday, and Wozniacki's first match of the tournament will be on Tuesday.
