Hollywood actress Reese is nursing a bruised foot,after she fell injuring herself in a jet-lag induced haze. The 'Walk the Line' star had just woken up from a nap after arriving in London last week when she tripped over herself but didn't feel any pain at the time because her foot had fallen asleep,Contactmusic reported. The 34-year-old actress however,braved high heels to make an appearance on UK talk show Friday Night with Jonathan Ross,where she showed off her bruises. "I think I broke my foot. I'm not sure,I haven't had a scan yet. I was taking a nap yesterday because I was real tired,I had jet lag. You know when your foot falls asleep. Then I stood up. Someone called me on the phone and I went to answer the phone,and I said,'Oh I tripped over my shoe or something!'," Witherspoon said. "I looked down and it was my foot I had tripped over! And I hadn't had a thing to drink! I was stone sober! Then it swelled up and now it's all black and blue," she added.
