Kardashian Twittered that she hadn't had time to hit the gym before showing off her bod.
"Up super early today! Wish I had time to workout today but straight to filming all day," she wrote at about 6 a.m. EST.
On Thursday, Rob Kardashian's ex girlfriend Adrienne Bailon told UsMagazine.com that "Kim is going to be fine either way" after calling it quits with Bush, 24. The two had dated on and off since 2007.
Kardashian and Bush have been denying via Twitter that they're hooking up with others.
Are they over for good? Maybe not.
"They are unsure of what will happen in the future," an insider tells Us.
