Kate Hudson was engrossed in conversation while Matthew Bellamy carried her bag a couple paces behind in Sao Paolo yesterday. The couple, along with Kate's son Ryder, are in South America while Matthew's band Muse plays a handful of shows. Kate, Matthew, and Ryder first popped up in Buenos Aires last week, where she was spotted letting loose by drinking a bit of wine while pregnant and sharing sweet PDA moments with her man. The actress has also played the role of family photographer during their adventures with her camera thrown over her shoulder at all times. Kate will be wrapping up her time on tour, since her promotional duties for Something Borrowed are kicking off soon. She'll be meeting up with our I'm a Huge Fan winner this weekend, so stay tuned for that fun!
