Los Angeles, Jan 18 (IANS): Reality TV star Khloe Kardashian has postponed her plans to have a baby with husband Lamar Odom.

The 28-year-old has been open about her struggles to conceive with her husband, and recently admitted that she was determined to get pregnant this year.

However, her 32-year-old sister Kim, who is expecting her first child in July with rapper Kanye West, told eonline: "She (Khloe) texted me the other day that thank god it's me, not her. She's not sure if she's ready."

"It's funny, you know, you think you want something so badly, then I think she kind of realised, 'I have time. I am 28. I am good.'," Kim said.

Khloe also hit back at speculation she is desperate to have a baby, especially now that Kim was having one.

She took to her blog to set the record straight.

"I am happily married to a wonderful man and fall in love with him more and more each day, and we'll have a baby when god wants us to and when the time is right," she posted.

She recently revealed she is starting off 2013 with a positive attitude.
