Pals Simon Curtis and Debby Ryan catch up inside the L.A. Friends of the Uganda Wildlife Authority Gorilla Awareness event held at Sony Pictures Studios in Culver City, Calif., on Monday evening (December 7).

Simon co-hosted the event with American Pie star Jason Biggs. The duo were just one of many who flew to Africa to participate in the campaign to save the endangered mountain gorillas, the majority of which live in Uganda.

The group will track the largest group of 36 gorillas, called Nshongi, at Rushaga in Bwindi Impenetrable Forest.

Debby and Simon also attended Variety‘s 2009 Power of Youth event held at Paramount Studios in Los Angeles.
