Celebrity Sex: Kate Upton's Smokin' Hot Body Tweet

It's not as easy as it looks being a two-time Sports Illustrated cover girl. So claims Kate Upton, anyway.

The 21-year-old model tweeted a bikini pic from the Bahamas on Tuesday with the caption, "Rough life." 

Upton is currently in Nassau filming scenes for the comedy The Other Woman with co-stars Cameron Diaz and Leslie Mann. The movie, set to be released in April 2014, also stars Nikolaj Coster-Waldau, Nicki Minaj and Taylor Kinney.

We can't imagine the stress of jetting off to Caribbean islands, frolicking in the surf on set, and maintaining the perfect bikini bod. Nope, can't imagine that at all.
