Khloe Kardashian Says She Feels Like a 'Hippopotamus' While Stepping Out With Kourtney in Racy Dresses for Ang

Despite their sizzling red carpet takeover, Khloe admitted on Snapchat that she felt like 'a beached whale' and was frustrated with her appearance at the charity gala on Monday.

Hello, Kardashians!

Khloe and Kourtney gave off enough mega-wattage at the Angel Ball to more than make up for the fact that their sister, Kim, couldn't be in attendance on Monday night.

The lovely ladies, who attended the New York City gala with their mom, Kris Jenner, showed a whole lot of leg and then some in two very racy dresses.

Khloe bared nearly all yet was still covered up in a sheer Yousef Al-Jasmi dress that featured silver branch-like sequined embroidery, while Kourtney wore a black strapless gown with a bustier top, ruffled skirt, and thigh-to-knee cut-outs along the sides of her legs. Both were adorned in Lorraine Schwartz jewels.

Even though the pair sizzled on the red carpet, Khloe apparently wasn't feeling great about herself. Despite showing off her dress on Snapchat earlier in the evening...

...once they were in a taxi to the event, the 32-year-old denim maven aired a few frustrations about how she looked. 

"Kourtney will not stop videotaping me, and I look literally like a hippopotamus and a whale had a baby. Mind you, Mario [Dedivanovic] said I look like a f**king ice skater, while Kourtney looks like gorgeousness..." Khloe said over a series of selfie videos.

She then turned the camera on her sister and exclaimed, "Look how bomb. Oh my god, see? Fuego, this one. Gorgeousness. Stunning angel."

In one of the many Snapchat videos Kourtney took, the mom of three even joked about Khloe not wanting to be videotaped, to which her sister replied, "Because I'm like a f**king beached whale and you're making it more difficult."

Then in a later vid, which the 37-year-old reality star dubbed "Taxi Cab Confessions," Khloe reiterated, "Why would I want to do a red carpet if I feel like a fat slob? Why would you?"

Once inside, however, Khloe got in the celebratory mood once again. After all, the charity gala benefits Gabrielle's Angel Foundation for Cancer Research, and last night's event memorialized her father, Robert Kardashian Sr.

The Kardashian family was seated at a table with Kris' boyfriend, Corey Gamble, family friend Jonathan Cheban, and Tommy Hilfiger, who presented a tribute video dedicated to the late attorney that was set to Kanye West's song, "Only One," and featured home videos. The memorial brought tears to Kris' eyes before she took the stage to accept an award on Robert's behalf, with Khloe and Kourtney standing by her side.

Kris, Khloe, and Kourtney later presented the foundation with a $250,000 check, which goes towards the charity's goal of finding new treatments and cures for cancer. As for Kim's absence, though she was rumored to be attending the event, which would have been her first major public appearance since being robbed at gunpoint in Paris in October, she reportedly skipped the event to be in Los Angeles following husband Kanye West's hospitalization.

Though the evening was an emotional roller coaster, Khloe and Kourtney found some solace in a favorite activity on Tuesday morning -- shopping! The duo held hands as they visited Tommy at his brand's headquarters, with Kourt even snagging a sweet '90s throwback jacket, which got a major smile out of the designer.
