"I'm just fat," Kardashian, 25, coyly told reporters clamoring for pregnancy news at a Los Angeles Lakers game Thursday at L.A.'s Staples Center.
Still, Kardashian, who was there to cheer on hubby Lamar Odom as his team took on the Boston Celtics in an NBA finals matchup, played up her maternal instincts. "It's exciting and an honor to see Lamar here," she said. "I'm like the proud mom, like, cheering him on and screaming."
Taking her courtside seat near brother Rob and sister Kourtney, Kardashian spent the evening kidding with fans. She also raved to PEOPLE about her marriage to Odom. "We're doing great," she said.
But when asked – point-blank – if she's expecting, the reality star demurred to comment directly. "I'm just watching the game," she said.
