Megan (The Pictures of Emptiness)

Megan was in charge of wardrobe on the set of Market Square. She helped the Tenth Doctor defeat the Vacant Mitra Ashkanzai, when she visited the set and stole the personalities of cast and crew while posing as a photographer standing in for Des Martin. In appreciation for her help, the Doctor posed for a digital picture of him in an Admiral's hat that he seemed so fond of, “the soap star that never was”. (TDL: The Pictures of Emptiness)
