Khloe Kardashian isn't pregnant - yet!- but she and husband Lamar Odom already have a baby name picked out.
"Boy, it would be Luke Joseph. The girl is on her," Odom, 30, told UsMagazine.com at the Power Balance Goes All-In For A Cure event at Drai's Hollywood Tuesday.

He admits they're trying to get pregnant: "When you're married you're supposed to try for kids."
When will it happen? "As soon as possible, I would think. I still want to be young when my kids are young." He is dad to Destiny, 12, and Lamar Jr., 8, with ex girlfriend Liza Morales.

Khloe, 26, will make a good mom, he says: "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."
(Khloe returns the compliment: "He has two kids so I know he’ll be a great father," she tells Us.)

Odom also says he's friendly with sister-in-law Kourtney's beau, Scott Disick, despite an episode of Kourtney & Khloe Take Miami that shows him trashing a condo after Kourtney accuses him of smoking marijuana.
"I always get along with Scott," says Odom. He also calls Kim's new beau, Miles Austin, "a great dude."
