Khloé Kardashian: Kourtney "Was Hyperventilating" Over Queso Dip

It seems 32-year old reality TV star Kourtney Kardashian has Mexican on her mind - at least that's what her younger sister claims.

The 27-year-old Kourtney and Khloé Take Miami star sat down with celebrity chef Rachel Ray on The Rachael Ray Show - which airs Wednesday - and opened up about her sister's crazy cravings during her visit to Dallas, Texas.

"She wanted to go somewhere, some Spanish restaurant," Khloé reveals. "She's pregnant and has been having cravings, and she couldn't get it out of her head!"

Although Khloé wanted her NBA player hubby Lamar Odom to join them after practice, it seems her pregnant older sister just couldn't wait.

"She was like, 'I cant. I'm just going to go and eat there twice,'" Khloé says. "And she was, like, hyperventilating, and I was like, 'Oh my God, it's just queso dip!"

"That's all she wanted," she adds. "She was a sweet little pie after that."

Kourtney is expecting her second child with partner Scott Disick. The couple are already parents to their 2-year-old son Mason.
