Zoe Saldana had sex on a train

Los Angeles - Zoe Saldana once had "super ghetto" sex on a train.

The 35-year-old actress, who admits she's made love on a plane before, revealed the craziest place she's ever had intercourse was in between two rail carriages.

Speaking on SiriusXM's Sway in the Morning, she said: "I am part of the Mile High Club. Ok this is ghetto, but I'm from Queens so whatever, there is a train from Coney Island, New York all the way back into the city, and it (the sex) was between two train cars, it was super ghetto."

However, the brunette beauty, who is married to Marco Perego, insists she's changed her ways and won't be getting physical on a public mode of transport again.

she added: "I'm a lady now."

However, Zoe - who dated Bradley Cooper until 2012, and also had an 11-year relationship with Keith Britton until 2011 - is no stranger to discussing her personal life as she revealed in 2010 she couldn't live without sex and thinks everyone should show off their body.

She said at the time: "Love it, love it, love it - can't live without it! I love sex. I love skin. I don't believe the body is something to hide."

And in May 2012, Zoe took things one step further by revealing her favourite sexual position.

She said: "I like missionary and I like being on my knees too. And I love being on top. I love doggy-style or standing up."
