Khloe Kardashian has put her baby plans on hold because of all of the recent upheavals in her life.

The former 'X Factor USA' host - who has not been asked to return for a second season - decided not to focus on starting a family with her husband Lamar Odom yet because she wants some time to focus on her marriage following a stressful year.

A source told HollywoodLife.com: ''Khloe has put her baby plans on hold for the time being, but that's still on her mind - a lot.

''She got fired from her hosting show, [she's had] complications getting pregnant, Lamar's basketball game was sloppy. Right now the last thing they need to do is another thing to their plate. Instead they'll just take some time to themselves and recharge.''

However, Khloe, 28, is excited about her 32-year-old sister Kim's pregnancy and plans to support her sister in any way she can.

The insider added: ''She will be there to support Kim through it all. She'll be at the hospital.''

Khloe - who has struggled to conceive in the past - previously revealed that her mother Kris Jenner, 57, offered to be a surrogate for her and Lamar, but she would find that ''too gross''.

She said: ''She did say it but I think it was more in a joking, passing way. I'm sure she would love to just because she's crazy. But, no, that's too gross!

''I mean I appreciate it but my mum ... isn't that, like, a little old to do that? Can't you only do that at a certain age?''
