"She's really great, I think she's finally feeling great about her pregnancy," the 28-year-old reality star said of her sister.
Kim, 32, has come under fire for everything from her pregnancy weight gain to her fashion choices in recent months, but according to Khloe, Kim is feeling more confident about her changing body now.
"There's an awkward time [when] you're not really showing and you don't feel like your old self. So now that her bump is alive and in full effect, she's having fun showing it off!" Khloe added.
On the red carpet at the MTV Movie Awards on Sunday, April 14, Kim turned heads in a flattering black Yves Saint Laurent frock that hugged her curves and showed off just enough skin with billowy sheer sleeves. The reality star completed the look with a long gold necklace that strategically emphasized her bump.
The Kourtney and Kim Take Miami star has had numerous Hollywood A-listers jump to her defense after she was publicly criticized for her body (As reported in the April 1 issue of Us Weekly, the reality star has been compared to Shamu and called "huge" and "fat") -- including former Victoria's Secret Angel Helena Christensen, Gloria Steinem and Jenna Dewan Tatum.
Kim's own pals have taken note of the cruel comments but tell Us that Kim isn't letting them get underwear skin anymore.
"In the beginning, all the comments really hurt her feelings," a close friend told Us. "She cried a lot and was down on herself. [But now,] Kim's choosing not to let them affect her."
