Sienna Miller walked her dog around SoHo, but was unhappy with the paparazzi attention. After getting into an argument with them, she ended up in tears and headed home.

Channing Tatum & Jenna Dewan

My dog is the best. She always finds celebrity dogs to befriend. On Sunday while hiking Runyon, she befriended the dogs of Jenna Dewan and Channing Tatum. Both of their dogs were sniffing Lula while I was reading the map and I paid no attention until all the leashes got tangled up and I heard somebody apologizing profusely. I looked up and saw the two of them and we started chatting. She has a fluffy white Pomeranian and he has a precious pit bull puppy with bright blue eyes. He said his pup is now 7 months old and gets a little nervous around others. Here's some pics that the paparazzi took on Sunday at Runyon.
