The 26-year-old beauty and her basketball player spouse Lamar Odom, 30, are to appear in an E! spin-off from `Keeping Up with the Kardashians` - in which Khloe stars with her sisters - which will focus on their life together as a couple. A source close to Khloe has revealed to website Gossip Cop the as-yet untitled series will show her "trying to get pregnant" and her day-to-day life being a wife and stepmother to Lamar`s two children Destiny and Lamar Jr. - his kids with ex-girlfriend Liza Morales. A representative for E! is yet to confirm the details of the new series. As well as `Keeping Up with the Kardashians`, Khloe has also appeared in `Kourtney and Khloe Take Miami` with her sibling. Kourtney admits things got tense between her boyfriend Scott Disick and sister Khloe during filming. Kourtney said: "He (Scott) got a little crazy in Miami. Khloe and Scott living together under one roof - we were all living in a suite - it`s just not a good idea. Things got a little intense."
