Los Angeles - Kim Kardashian is reportedly taking her personal trainer on her honeymoon.
The Keeping Up With The Kardashians star, who is expected to tie the knot with fiancé Kanye West in Paris next month, has been working hard to get in shape for the wedding and is said to have asked her trainer Gunnar Peterson to travel with them to Hawaii as she doesn't want to let herself go.
A source told the Daily Star newspaper: "Kim has paid for Gunnar to come along so she can work out while she's away on her honeymoon.
"Kim doesn't feel happy when Gunnar's not around as she loses her willpower so quickly.
"She doesn't want to undo all her hard work and pile on the pounds on the honeymoon."
The 33-year-old star got engaged to her rapper fiancé, 33, last October following the birth of their daughter North, and he's said to be more than supportive of her plans to carry on her fitness regime.
The source added: "Kanye totally gets it, he's completely supportive of Kim's efforts to lose the baby weight and get in shape for the wedding.
"North will stay with Kim's family and her nanny.
"Kim and Kanye want time away from parental duties as it's important for them to spend time alone as a couple."
Meanwhile, it's been revealed that Kim has not yet sent out the invitations for her nuptials, as she wants to keep the location a secret.
A source told HollywoodLife.com that 90 guests will soon receive a card printed with "a date and Paris" and will only find out where the couple will exchange vows when they check in to their chosen hotel in the city.
