Kim Kardashian thinks age is no barrier to love.

The 29-year-old star - who recently insisted she was not romantically interested in 16-year-old Justin Bieber - believes the key to a successful relationship is making a "connection".

She said: "The oldest I'd date? I once went out with someone who was almost 50. I do like someone young and fun, but not 16 young, more like 26 young.

"Whoever your soul connects with, whoever you fall in love with no matter what the age. However, it might seem good when you're 25 and they're 50 but when you're 50 and they're75."

The brunette beauty believes she never went off the rails when she was younger because her father wanted her to be "responsible" for her older sister Kourtney Kardashian, and even taught her to drive when she was just 14.

She explained to US TV host Jay Leno: "I've never been a drinker, I've never gotten into drugs, I have such a close family. My sisters do enough drinking to fill up the whole family so from a young age my dad made it clear I was the responsible one.

"And he taught me how to drive when I was 14 in case my sister or her friends were going to be drinking, and I had always had permission to drive, or else I had to call him from the destination to the final place...So I always felt this sense of pride that he had In Me as the responsible one, so I've always wanted to make him proud."

However, the reality TV star - who is dating NFL player Miles Austin -has finally found an alcoholic beverage she likes after promising her sisters she would be "less boring" before reaching 30.

She explained: "I hate the taste of alcohol."

"I did say that, at 30, I'm going to have a drink to lighten up because my sisters say I'm so boring. So I tried a White Russian a few months ago...It tastes like chocolate milk, and it's kind of amazing."

A White Russian is a cocktail made from vodka, coffee liqueur and milk.
