She’s a former Playboy model so certainly isn’t shy about stripping off.

So when one of Kendra Wilkinson’s best friends celebrated her 30th birthday, the blonde star was quick to come up with a naked way to celebrate.

An image posted on Twitter shows mother-of-one Kendra stripping down to a white thong as she makes a dash into the water alongside her friend Jessica Hall.

A very cheeky way to celebrate! Kendra Wilkinson stripped to a white thong to go skinny dipping to mark her friend’s 30th birthday

Jessica, who posted the shot on her Twitter page before it was retweeted by Kendra, wrote alongside the shot: ‘Skinny Dipping in big bear with @KendraWilkinson making a splash in my 30’s haha #dirtythirty.’

Kendra no doubt also used the occasion as an opportunity to show off the swimming and diving skills she learned as part of her involvement on hit US TV show Splash!

The skinny dipping session came as part of Kendra’s holiday with husband Hank Baskett to Big Bear Lake, in Southern California.

Adding to the family: Kendra’s husband Hank Baskett was also on the trip, and the model said the pair decided on the vacation that they wanted to give their three-year-old son a brother or sister

And Kendra, who is mother to three-year-old son Hank Baskett IV, recently revealed that she and Hank decided to use the vacation to try for another baby,

Kendra told People magazine: ‘On our week vacation in Big Bear, we found this new energy with each other, a new love, a new fascination about each other.

‘And right now, we found the key to happiness. We have the key to marriage, we have the key to parenting, why not, right now, bring a new life into this world while we’re this happy? It just makes sense.’

Kendra – whose reality show, Kendra On Top, hits screens later this summer on WeTV – has been thinking about having another child for some time, because raising Hank Junior has been such a delight.

Speaking previously, Kendra said: ‘Hank is in school, he does homework and he’s taking swimming lessons.

‘He uses his imagination and doesn’t even want to watch TV. He’s the most amazing little human. He’s making us feel comfortable about baby number two.’
