The song was one of the year's inescapable hits, and the video – notably featuring a topless Ratajkowski – has been viewed more than 257 million times.
Such a reaction has led many to speculate that Sports Illustrated would be featuring Ratajkowski in its 50th anniversary swimsuit issue, which hits newsstands Feb. 11.
In December, veteran SI swimsuit-issue editor MJ Day posted Instagrams of a brunette model on a tropical shoot, though stopped short of identifying Ratajkowski.
Coincidentally, the same day editor Day was Instagramming maybe-Ratajkowski, the model herself put up a photo from some tropical location, saying she'd arrived in "paradise."
This prompted photographer Dax Balladares to Tweet a possible spoiler at Ratajkowski.
