Pregnancy struggle: Khloe Kardashian is desperate to have children with her husband Lamar Odom
Khloe Kardashian has admitted that she is 'freaking out' about her struggle to get pregnant.
The reality star and husband Lamar Odom have been trying to conceive for some time and in the final installment of their show, Khloe & Lamar, she finally crumbles under the pressure following another round of fertility testing.
She tells Lamar: 'I'm sorry for snapping at you and being on edge lately but I've been holding a lot of stuff in and trying not to bother you, but I've been freaking out about why I'm not pregnant.
'It's scary [thinking], "Oh God, what if I physically can't have kids".'
Odom, who married Khloe in 2009 after just 32 days together, was more optimistic.
'It'll work out. If something is wrong, that doesn't affect anything [we're] going to do [as a couple],' he said.
'We're not going to give up.'
Odom has two children, Destiny, 12, and Lamar Jr., 8, with his ex-girlfriend Liza Morales.
In June 2006, their 6-month-old son Jayden died from SIDS while sleeping in his crib.
Morales, who split from the LA Lakers player in 2008, recently accused him of not being involved in his children's lives.
'Financially, Lamar has always been very giving,' she told America's OK! magazine. 'But as a father, he has been very inconsistent.'
Morales says she moved to LA following their break-up so they could spend time with his father.
'For a period of 11 months, he saw the kids about five times,' she claims. 'So I moved back to New York, where we have other family.'
