Kendra Wilkinson wants to have the "best booty in Hollywood".

The 24-year-old former Playmate - who gave birth to first child Hank Baskett IV in December - is determined to get her pre-pregnancy figure back as she wants to look as good as socialite Kim Kardashian.

Despite rumours of a rift between her and the 'Keeping Up with the Kardashians' star, the model insisted: "I know people think we're fighting, but it's so stupid. Kim Kardashian can be my motivation to try and have the best booty in Hollywood! I'm doing squats and whatever it takes to keep my new butt." Although she's always been confident about her body, the new mum does admit having nerves about getting back into a bikini, which she did for a recent magazine photo shoot.

She said: "Getting into a bikini in only weight weeks was definitely nerve-wracking!"

Kendra admits her weight loss regime is going well, but she is refusing to weight herself to see exactly how much she has lost.

She said: "I've lost around 25 pounds, but it has nothing to do with the scale... I'm going based on how my clothes are fitting."
