First they hit the NBA Finals together in Miami. Then Serena Williams and Caroline Wozniacki were besieged with questions about being "gal pals" at the U.S. Open. By the end of the fortnight everyone wondered, would their friendship survive their championship showdown?
They were clearly able to Shake It Off just fine, hitting a club together just hours after Williams beat Wozniacki in straight sets to win her 18th Grand Slam title. The world seemed to be slightly less Obsessed with the friendship for the past few weeks, but now they're back to say Don't Forget About Us!
Hours before they face off in the WTA Finals semi-finals on Saturday, Williams and Wozniacki posted a selfie at a Mariah Carey concert. One Sweet Day everyone will just let them be friends without it making headlines. But for now, it's pretty obvious that we Can't Let It Go. More than 8,000 fans liked the post within two hours.
They also posted a video of Mariah, in which you can hear them singing along to "We Belong Together." After the show, they both posted pics with their other pal, Mariah.
