Kim Kardashian looked smashing in a white-hot bikini Sunday while vacationing with beau Reggie Bush in Costa Rica.On Monday, she Twittered that she had a photo shoot Tuesday and asked fans for advice."Do I get up at 6am to workout or sleep that extra hour to and look more rested. Toned or rested???" she asked.She was pleased with the responses.

"Not ONE reply said to workout!" she said. "Everyone said sleep and be rested. Usually its like half and half but not this time!"In the end, Kardashian said she ended up doing sit ups and squats at home for 30 minutes. "Best of both worlds," she wrote.
