Miranda's only appearence in TBOGT, was in one of the trailers for the game. The trailer is a report from the show Fizz!, in with they describe the nightlife of Liberty City. She appears as one of the many celebrities that frequents the Bahama Mamas nightclub.
Her appearance is drastically different in Grand Theft Auto V compared to The Ballad of Gay Tony. She is blonde and appears much thinner in 2008 compared to 2013. This could imply that she gained weight and/or dyed her hair but it is more likely a development oversight.
