Barack Obama is on a visit to Africa, first visiting Kenya where his father was born, then to South Africa where he gave the 16th Nelson Mandela annual lecture.
Obama spent time with his extended family while in Kenya, launching a youth sports centre built by his half-sister Auma.
The former president, however, spent some time with his step-grandmother also, and having fun in the process.
Obama showed off his dancing moves while with his 96-year-old step-grandmother, standing to dance only for a few seconds.
