Khloé's little sisters, Kendall and Kylie Jenner, think it'll happen sooner than later.
"I know Khloé has always wanted to have kids, because when me and Kylie were little, she would babysit us," 13-year-old Kendall told us last night at Onitsuka Tiger's record release party for Selena Gomez and the Scene's debut album, Kiss & Tell.
"She was like our second mom," she said. "I know she'll be a great mom."
Kylie, 12, added, "I just can't wait for her to have kids!"
As for how Lamar is fitting into the big Kardashian-Jenner bunch…
"The first time I met [Lamar], he gave me a hug," Kendall said. "He's the nicest guy. I know I keep saying that, but it's true."
Describing Lamar as "family now," Kylie said, "You can't control love. They're in love with each other. I think they're a great couple. I think it's going to last their whole life."
Even though Kendall said it may be a little hard for Kim to watch Kourtney having a baby and Khloé getting married because "she thought she was going to be the first," sounds like everyone is hoping her reunion with Reggie Bush sticks.
Kendall gushed, "I love Reggie."
