The actress and writer rose to fame in 2012 after creating and starring in the U.S. series about the chaotic lives of Hannah, Marnie, Jessa and Shoshanna, four young women living in New York City.

The 30-year-old star jokingly admits that the inspiration for her candid semi-autobiographical comedy-drama came from an unlikely source.

Appearing on America's Late Night with Seth Meyers TV show, Lena recorded a message to her younger self, in which she says, "Hey little Lena, this world is full of magic and wonder. You're going to live life to the fullest and one TV show about four friends will change your life forever."

The 30-year-old star then paused before revealing, "That show is called Teenage Mutant Ninja Turtles. Basically you're just going to rip it off wholesale. Hannah, Marnie, Jessa and Shosh are pretty much just Donatello, Raphael, Leonardo, and Michelangelo with vaginas."

She continues, "So in a couple of years when you're in a pitch meeting with (U.S. cable TV network) HBO, just blurt out, 'Teenage Mutant Ninja Turtles but the turtles are girls!' They'll give you a blank cheque faster than you can say, 'cowabunga, dude'."

Beginning life as a comic book in 1984, the first TV adaptation of Teenage Mutant Ninja Turtles was a cartoon series which ran from 1987 to 1996. A live action iteration also aired in the U.S. in 1997 and 1998.

As Lena states, like Girls, the show did feature four main characters, Donatello, Raphael, Leonardo, and Michelangelo, although they were wisecracking mutant reptiles rather than angst-ridden aspiring creatives.

Both programmes were set in Manhattan, although the turtles' main adversary was the supervillain The Shredder rather than thoughtless boyfriends.

In addition to the TV adaptations, the Teenage Mutant Ninja Turtles are also about to arrive in cinemas for the sixth time, as the latest movie featuring the characters, Teenage Mutant Ninja Turtles: Out of the Shadows, is set for release in the in the U.K. on 30 May and in the U.S. on 3 June (16).
