Khloe Kardashian and Lamar Odom hoping for baby

Khloe Kardashian and Lamar Odom are "practicing" for a baby.

The 25-year-old reality TV star and the basketball player got married in September but are already asking friends if they can babysit their children.

Former MTV host La La Vazquez says Khloe has been begging to look after her two-year-old son Kiyan for weeks.

La La said: "We have a joke, that she's got to take Kiyan for a few days to practice. They'll be begging me to give him back!"

La La claims Khloe and Lamar - who got engaged after just one month of dating - often talk about starting their own family.

"Khloe is happy, strong and in a great relationship," she said. "There aren't two people more perfect for each other."

Lamar, 30, already has children Destiny, 11, and seven-year-old Lamar Jr. with his ex-girlfriend Liza Morales.

The couple had another child, Jayden, who died of Sudden Infant Death Syndrome (SIDS) in 2006, aged just six months.
