Venus Williams has seen it all in her storied career.
Still, seeing Grigor Dimitrov flash his six-pack floored the former world No. 1.
Venus, who has been conducting virtual fitness classes on Instagram, goaded Grigor into showing his ab-tastic form.
When the Bulgarian complied, Venus was knocked off her feet.
The four-time Olympic gold-medal champion once named Nick Kyrgios as her dream mixed doubles partner, but maybe we can dream about a Venus-Grigor Grand Slam doubles pairing someday.
