For quite some time now, Serena Williams has been trolling her big sister on Snapchat for wearing only short skirts and dresses. But this week, the tide turned, with Venus rocking pants (for the first time in years, at least according to Serena).

"Venus, how does it feel to wear pants?" Serena asked. "I mean, they're low riders but still..."

Ah, multiple Grand Slam-winning, record-breaking sisters, they're just like us. If you're not following Serena on Snapchat, you really should be (@serenaunmatched).
