Khloe Kardashian Says It's 'Perfect Time' For Kourtney's Baby

Will Khloé have a new niece or nephew? 'Either way, the baby is going to be so cute,' she tells MTV News.

Next year is gearing up to be another busy one for Khloé Kardashian. The "Keeping up With the Kardashians" star will be making the move from Los Angeles to Texas following husband Lamar Odom's trade to the Dallas Mavericks, and she will be helping big sister Kourtney get ready for baby #2.

Just last month, Kourtney Kardashian announced she was expecting her second child with longtime boyfriend Scott Disick. MTV News caught up with Khloé at Z100's annual Jingle Ball concert, where she said that her big sister has been feeling a little under the weather during her pregnancy.

"She's good. She's a little more nauseous this time around, which I feel bad about, but she's great, and it's so exciting," Khloé said. "She doesn't have any belly yet, of course — only her — but Mason's second birthday is coming up [Wednesday], so it's crazy. But I think it's the perfect time for her to add another baby. Mason's old enough."

Does Khloé know if Mason will have a little brother or sister? "I have no idea," she said. "Either way, the baby is going to be so cute."

When news of Kourtney's pregnancy was announced, Khloé took to her blog to express her elation over the news. "I am BEYOND thrilled to fiiiiinally be able to share with all of you the fabulous news that my beautiful big sister Kourtney is expecting yet again!" she wrote. "Can you believe it?! Masey is going to be a big brother! We are all so overjoyed by this wonderful news and are counting down the minutes until we get to meet the newest member of our family."

Kourtney, Kim, Scott, Mason and Kim's soon-to-be ex-husband Kris Humphries are all currently starring on the second season of "Kourtney & Kim Take New York."
