London Zoo are celebrating the birth of a new male gorilla!
The baby was born on Tuesday, and is thought to be doing well. Mjukuu - the baby's mum is recovering well too.
The zookeepers say her sisters Zaire and Effie were at the birth and have stayed with her throughout.
The new gorilla, which hasn't been named yet, is going to be introduced to his stepfather Kesho by the zookeepers. His real dad died some time ago.
The gorilla might look tiny now, but will grow up to become a 25 stone silverback gorilla!
