Rumors were mounting over the weekend that Butler and Diaz have been enjoying a string of secret dates. It's been claimed that both stars have been on three dates in just ten days, being spotted at Teddy's Bar in the Roosevelt Hotel, having a romantic dinner at The Chateau Marmont hotel and were seen sharing drinks at Shutters Hotel.
A witness claimed to have seen the pair "walked up to the balcony area to look at the sunset. He had one arm round her waist and the other on the small of her back. She kept giggling and touching his chest to whisper in his ear. They obviously had a good night."
Butler, during his morning run in Los Angeles on Thursday, April 10, nevertheless quashed the rumors, saying "So if I take my dog for a walk apparently I'm f-ing my dog? No, it's not true!"
