Hugh Hefner's three girlfriends are like the "Spice Girls". The 82-year-old Playboy founder has three live-in-lovers - Kendra Wilkinson, 23, Holly Madison, 28, and Bridget Marquardt, 34 - and Kendra claims it is the girls' differences which help the quartet stay close.

She said: "If we all wanted the same thing it wouldn't have worked, because that's where all the drama would have started, but we're like the Spice Girls - I'm the sporty one. "We are on different roads and they don't intersect. We don't spend time together every day - girls just can't do that." Kendra also claimed the group stay close by regularly spending time apart.

She added to Fox News: "We are three very different people - we're doing very different things with our lives and we don't step on each other's toes." Kendra also hinted her time as one of Hugh's lovers might be coming to an end because she feels ready to adopt a more orthodox lifestyle.

She said: "I was only 18 when I first moved in and I've grown up so much. I really have a new light on my life. "I've been thinking a lot about marriage and kids - I don't care about going crazy and partying anymore. I'm focused on the real life things, my future. That's who I am now."
