Reality babe Kerry Katona is putting plenty of money into her Celebrity Big Brother 2011 appearance, with her latest spend seeing her have a teeth whitening. Kerry, who is set to enter the house tomorrow night, is said to be after the perfect body and look to show off in front of the cameras.

And with 42 of them all filming in HD, it's not surprising she wants to look her best.

The former Atomic Kitten singer - who previously won ITV’s I’m a Celebrity Get Me Out of Here - is one of twelve celebrities entering the first series of Celebrity Big Brother on Channel 5, when it launches tomorrow night.

Pals of the star have revealed how Kerry, who has battled drink and drugs in the past, has been trying to shift weight in order to look her best, especially next to stars including Amy Childs and Pamela Anderson.

"She has always had battles when it comes to her weight but going into Big Brother has given her a goal and kept her motivated,” a source said earlier this week.

They added: “Not only is she really slim at the moment, she’s also really toned, with even some light muscles.

Having hired a personal trainer in order to lose almost a stone in a few weeks, it sounds as though Kerry could well spend her reported £200,000 fee before she even enters.

Kerry said: “I am both nervous and excited about going into the Big Brother house. But knowing I have nice, white teeth that I can dazzle the audience with will boost my confidence.

“I’ve been to boot camp and got myself into great shape and with the help of Johann and Eben my teeth are looking great too. I am ready to give it my best shot.”

Other celebrites lined up for the show include R&B star Bobby Brown and American Pie actress Tara Reid.

The new-look Big Brother kicks off with Celebrity Big Brother 2011, tomorrow at 9PM on Channel 5.
