Mila Kunis says rumours linking her to Ashton Kutcher are "bulls**t and lies".

The brunette beauty has been spending a lot of time with her former That 70s Show co-star, setting tongues wagging that she is dating Demi Moore's estranged husband.

The actress insists that the majority of media reports about her personal life are false and blasted paparazzi.

"Ninety-nine per cent of it is bulls**t," she said when asked about the speculation surrounding her and Ashton. "That is the biggest form of bullying ever, the paparazzi. Printing lies, making accusations, it's just bullying."

While Mila is officially single for now, she enjoys playing cupid for her friends.

The Black Swan star revealed that she regularly checks out online dating sites and chooses potential dates for pals.

But Mila explained that signing up herself is not an option.

"I love those sites. I go on and I pick the guys for my friends. I think it's great. It's online shopping! We all get together with our laptops and have a glass of wine. Then we message the guy," she said. "I'm really good at About Me'. I feel like I could never write anything about myself, because that's like a therapy session If I didn't do what I do, I would do Internet dating instead of going out to bars. In two seconds I would. It makes so much more sense.

"[But I can't] Because, ultimately, what's going to happen? I show up to coffee I'm OK in my personal life. I've never dated. I can say this honestly: I don't know what it's like to date. But also, how am I going to date? I'm not in one state long enough."
