WATCH | A winner of 17 Grand Slam singles titles, Roger Federer's a natural when it comes to tennis skills. But as the Tennis Channel has discovered, his boy-band swag may need a bit more work. (Full disclosure: Tennis Channel is owned by Circa's parent company, Sinclair Broadcast Group.)
Before advancing to the Australian Open quarterfinals, Federer joined Grigor Dimitrov and Tommy Haas at a piano.
The makeshift boy band teamed up for Chicago's 1982 hit "Hard to Say I'm Sorry."
"We're starting a boy band #NOTNSYNC," reads the caption to Federer's Instagram post. He shared similar insight in Twitter and Facebook posts, the latter of which had almost 3.5 million views as of Monday afternoon.

Tennis Channel also chronicled Mary Carillo and Lindsay Davenport's shark summit.
