Khloe Kardashian has already chosen the name for her future baby.

The 26-year-old socialite and her basketball player spouse Lamar Odom, 30, are trying for a baby and have decided they want to call their son Luke Joseph.

Speaking about potential names, Lamar said: "If it's a boy, it would be Luke Joseph. The girl is on her."

The sportsman - who already has two children, Destiny, 12, and eight-year-old Lamar Jr., with ex girlfriend Liza Morales - is desperate to have children with Khloe, adding to "When you're married you're supposed to try for kids. As soon as possible, I would think. I still want to be young when my kids are young."

The 'Keeping Up with the Kardashians' star - who has five siblings and four step-siblings - recently revealed she is hoping to get pregnant this summer but accepts it is "up to the gods".

Lemar isn't worried about Khloe being a mother, because she has had lots of practice taking care of him.

He said: "She's got an incredible relationship with her two younger sisters. She has maternal instincts. If she can take care of me, she can take care of a baby."
