Mhaegen is a recurring character in the first and second seasons. She is played by guest star Antonia Christophers and debuts in "The Wolf and the Lion." Mhaegen is a prostitute and the mother of the royal bastard Barra.
Mhaegen is a prostitute working and living at a brothel in King's Landing. She works for Lord Petyr Baelish. She is known to King Robert Baratheon and is a former favorite of his. They have an illegitimate daughter named Barra.
Goldcloaks led by Lord Janos Slynt break into Lord Baelish's establishment, along with a man who identifies Mhaegen as the mother of one of King Robert's bastards.

In the books
In the A Song of Ice and Fire novels, Mhaegen appears but is not named. She has a a light red hair and freckles on her nose and bosom. Ned estimates she cannot be more than fifteen years old.
She is killed by Allar Deem, a goldcloak sent by Lord Slynt, when she tries to protect her baby daughter. She was not explicitly shown to be killed by the goldcloaks in the TV series, thus her status in the TV continuity is uncertain. In the next episode, Ros mentiones to Littlefinger that Mhaegen "works for him" and that "the Gold Cloaks killed her baby" so she most likely survived the encounter.
