It's lonely at the top! Kate Upton, whose racy Arctic photo shoot landed her the much-coveted cover of Sports Illustrated's swimsuit issue for the second year in a row, is finding fame a little isolating. As the March 4 issue of Us Weekly reveals, the blonde bombshell's fellow pinups are not her biggest fans -- and that's putting it nicely.
"The SI models hate her," an insider tells Us of the voluptuous cover girl, 20. "They are jealous, but Kate's also been a bitch to them in the past."
In fact, things are so icy between Upton and the other models that they won't socialize with one another even when they're sitting just a few feet apart. At a 1Oak party in Las Vegas on Feb. 14, Upton kept to herself while the rest of the ladies chatted among themselves. "She didn't interact with anyone," an onlooker says. "She wasn't friendly."
For more on Upton's enemies, watch this week's Hot Stuff video, as explained by Us Weekly entertainment director Ian Drew and special guests Tommy Mokas and Tommy London of The Dirty Pearls, who give Us an update on pal Lady Gaga's recovery from hip surgery.
