Sandra Bullock was dressed in low-key sweats as she left an appointment in LA yesterday. Sandra and her son, Louis, arrived in California earlier this week; though, the adorable little guy didn't come along for mom's meetings. Sandra has been focusing on the most important guy in her life, Louis, but also spending time with good friend Ryan Reynolds in recent months. There were rumors of romance between the two, but Ryan's now being linked to Olivia Wilde after the two were spotted together in NYC last week. Even if Ryan and Sandra's relationship is only platonic, they'll be teaming up again with work — they're reportedly costarring in Most Wanted and are also working together on an animated series.
