Twin travel buddies! Fresh off her Golden Globes appearance on Jan. 11, Kate Hudson visited Mexico on Jan. 19, with her eldest son Ryder, 11, to do some charity work. 

“Ryder and I decided to take a trip to Mexico to help @starkeycares fit hearing aids to those in need,” the Good People actress, 35, captioned a picture standing next to her look-alike son, who’s father is Hudson’s ex-husband Chris Robinson of the Black Crowes, via Instagram. “Seeing the smiles of people hearing clearly for the first time has been an amazing and spirited experience. Thank u for allowing us to be apart of this mission. #Starkey #StarkeyCares #SoTheWorldMayHear.”

The pair wore tan hats and black fanny packs (not to mention their matching grins!). The mother-son duo were doing work for the Starkey Foundation, which provides hearing aids to children around the world. 

Last fitting of the day with sweet Eric! Thank u Bill Austin ???? #StarkeyCares #SoTheWorldMayHear

Hudson recently split from her longtime fiancé Matt Bellamy with whom she shares son Bingham, 3.
