Sandra Bullock was immersed in a phone conversation as she walked out of a friend's house in LA yesterday. She's back on the West Coast after traveling to Wyoming where she was spotted on a hike with pal Ryan Reynolds and her son Louis. Ryan and Sandra were spotted on vacation at Sandra's dad's house in Jackson Hole and during their stay they were also seen sharing a relaxing dinner at Rendezvous Bistro. The duo are apparently still just friends, despite the seemingly romantic trip. Now that the getaway is over, Ryan will get to work on his next project, RIPD, while Sandra has Extremely Loud and Incredibly Close's early 2012 release and little Louis to keep her busy.
