Los Angeles - Khloe Kardashian and Lamar Odom are "taking a break" from trying for a baby.
The couple - who married in September 2009 and star in their own reality TV show, Khloe and Lamar - have been trying to get pregnant ever since they tied the knot but now basketball star Lamar wants them to stop so he can concentrate on his career.
A source close to Lamar - who recently moved to the Los Angeles Clippers after being traded from the Dallas Mavericks - said: "Khloe and Lamar are taking a break from trying to have a baby while he settles into his new job back in LA.
"Lamar said that he and Khloe were trying for a baby, but admitted that he's not ready because he needs to give his all to his game."
'Feels like a failure'
While Khloe is supportive of his decision, she is blaming herself for the situation.
The source added to America's In Touch magazine: "Khloe feels like a failure."
Khloe - who is thought to have undergone fertility treatment - has made no secret of her desire to have a baby but admits she was feeling under pressure to conceive.
Speaking last year, she said: "People keep saying, 'Why aren't you pregnant yet?' That's what scares me, when people are like, 'Did you go to the doctor? Do you know if everything's working?' It's nerve-racking. Sometimes I feel like I'm letting everyone down."
Lamar already has two children, Destiny, 13, and 10-year-old Lamar jnr, from a previous relationship.
