Khloe Kardashian Odom is putting those pregnancy rumors to rest.
Asked at the Lakers/Celtics game Thursday if she's expecting, she told Entertainment Tonight: "No, I'm just fat."
Earlier this week, RadarOnline reported that the E! reality star, 25, is two months pregnant with husband Lamar Odom's baby.
But at Thursday's Lakers game, her mother Kris Jenner told UsMagazine.com: "If Khloe is pregnant, I would be the first to yell it. So, no, she's not — unless they're holding out on me, in which case they're both grounded."
Added brother Rob, "She's not pregnant. I live with those two, and I would know if she was pregnant."'
But mom Jenner told Us when the time comes, "she'll be the best mom in the world. She helped me raise Kendall and Kylie. I couldn't have done it without her. And [Lamar] will be a great dad. He's got two beautiful children. I can't wait until the rest of my kids have kids of their own, but right now we have little Mason, and I'm very, very happy."
In February, Khloe admitted to Steppin' Out magazine that while she was "not on the pill," she wasn't in any rush to become a mom.
"We're just being a healthy married young couple," said Khloe, who will celebrate her one-year wedding anniversary in September. "I'm not sitting here staring at an ovulation calendar. I'm not saying to Lamar, 'Okay, it's time, let's go!'"
