Ryan Seacrest and Julianne Hough were arm in arm yesterday for a walk in NYC. She accompanied her boyfriend on the trip to the East Coast, where he shot a cameo for New Year's Eve. He was occupied with the movie on Monday night, as he was spotted filming a Times Square countdown scene with the city's mayor, Michael Bloomberg, that was reminiscent of Ryan's real-life tasks on December 31. Ryan even tweeted to fans that he was happy to have rehearsed the role beforehand. His stint on set freed up Rock of Ages star Julianne to catch up with old friends, though she's been plenty busy lately between her date nights with Ryan and their global jet-setting.
