And what better way to celebrate her move home than for the Playboy pin-up to show off her fabulous figure in a bikini photoshoot.
Despite being only four months away from her 40th birthday, the blonde is looking as good as ever.The mother-of-one showed off the results of her workout regime following her recent nude shoot for Plaboy.
For her poolside shoot, she opted for a black and white polka dot bikini she bought from the Kardashian Khaos boutique during a recent trip to Las Vegas.
In a recent interview, Jenny explained her reasoning for returning to the Midwest.She told OK! magazine: 'I'm from there and I feel like my son is not getting the childhood that I wanted in LA.
'On top of that, I met someone I like and care about, so all those things combined takes me back home.'
As well as her son, Jenny also has another incentive to move back to Illinois - she is dating Chicago Bears American football player Brian Urlacher.However, she said her son isn't impressed by Brian's sporting fame.
She said: 'My son doesn't watch football. He judges people on their spirit, which is perfect.
'The relationship is still new, but my son loves being back in Chicago with his friends. His happiness is the most important thing to me - and my mom and dad live there - so, we'll see how the relationship develops.
