Khloé Kardashian was hurt by the secrecy over her sister Kim's pregnancy.
The Keeping Up with the Kardashians star ? who’s struggled to conceive a child with her husband, Lamar Odom ? admits she was deeply "offended" when she discovered her siblings Kim and Kourtney deliberately tried to keep news of Kim's impending motherhood from her in case she got upset.
During an appearance on The Tonight Show with Jay Leno this week, she explained, "I found out by watching Kourtney and Kim Take Miami that Kourtney said, 'This is going to push Khloé over the edge and we can't tell her.' I got offended by that.
"Of course I would be happy for my sister to have a baby."
The 28-year-old star also opened up about her own ongoing attempts to get pregnant, admitting she feels "pressure" to have a child with her basketball player spouse.
She said, "Everyone puts so much pressure on Lamar and I to have kids and I do feel that pressure. I went to the doctor and figured out that I need to use hormone injections.
"But I'm very happy. I'm 28 and I've been married for almost four years. I'm happy just practising [making] a baby for now!"
Khloé revealed her mother, Kris Jenner (57), offered to be a surrogate for her and Lamar, but she’d find that "too gross".
She added, "She did say it but I think it was more in a joking, passing way. I'm sure she would love to just because she's crazy. But no, that's too gross!
"I mean I appreciate it but my mom . . . isn't that, like, a little old to do that? Can't you only do that at a certain age?"
