Ghostbusters star Dan Aykroyd is convinced aliens are already here - and that they want to have sex with human women.

The actor says he's seen four UFOs and that most extra terrestrials who pop by Earth are just tourists coming to "look at this beautiful planet".

However, the star is concerned that some aliens want to harm people and use them as "lab rats".

And Dan is convinced that 60% of us already "know it's true".

He told the Daily Star : "The proof is going to start dribbling out. The aliens are interested in your ova, your femininity, your reproductive parts, your DNA.

"They would love to draw blood and fluid and would love to impregnate a woman and produce a hybrid baby, this is what they're up to here."

He added: "I believe some aliens are here to harm us. There are many that come here with nefarious purposes and want to use us as lab rats."

The Blues Brothers actor, 66, isn't the only star who has spoken about their alien encounters.

Former model and ex-wife of Rolling Stones star Ronnie Wood, Jo Wood, has been open about her belief in the extra terrestrial too.

She recently appeared on This Morning to talk about her new podcast Alien Nation.

Jo said her fascination with the extraterrestrial started at around age 12 when her dad was reading a magazine called 'Is God an Astronaut?'

Jo, 64, told hosts Holly Willoughby and Phillip Schofield about the time she saw a UFO in Brazil.

She was with Ronnie at the time when he shouted for her to come outside because he'd seen something in the sky.

She said: "I went outside and there over the sea was this shape that had lights that just came down and reflected onto the sea."

She said the lights shot to one side before disappearing quickly.

"The next day I stood there and thought, 'I have just seen a UFO'," she said.

"It was on the front of the paper that hundreds of people had seen the same thing."

Jo went on to say she also saw a UFO when she was on a plane with her son Tyrone.

She said she and her son were looking out the window and saw "this weird orb, a bluey green thing".

She said: "Ty goes, 'Mum, did you see that? What the hell was that?' It was very strange."

Jo said she's "not scared" of aliens and just wants to know more about them.

"I'm fascinated by the universe and by space," she added.
