Kim Kardashian vs. Rita Ora Beef, Kanye West's Baby Mama Flaunts Same Sexy Pink Latex Dress As Brother Rob Kardashian's Ex-Girlfriend! Fashion Battle PHOTOS/POLL

Rita Ora once dated Kim Kardashian's younger brother Rob - they actually went through a rather nasty break-up. Therefore, it's no huge surprise that North West's mama and the "Party and Bullsh*t" songstress aren't exactly friends. Which makes this epic fashion moment rather awkward!

Both stunning ladies flaunted VERY similar dresses while attending the same event earlier this week (February 26)! Kardashian and Ora arrived to the Mert & Marcus "House of Love" party at London's exclusive celebrity hot-spot Annabel "sharing" this sexy get-up:

Oops! Obviously, Kardashian's bootylicious body managed to "fill-out" the tight, latex dress a bit more. But Ora still looked gorgeous! Her version of the bright pink ensemble was a bit more "rocker chic."

Neither Hollywood bombshell has yet to remark or joke about the silly fashion mishap on Instagram. Instead, the "Keeping Up With The Kardashians" starlet continues flaunting love for her fans and hubby, Kanye West:

kimkardashian: "27 mil!!!!! Thank you so much!!!! I love you all!!!!"

kimkardashian: "He got it on his wrists instead. His mothers birthdate and North's birthdate in Roman numerals."

Meanwhile, Ora still thinks she looks pretty hot (without having to compare herself to the former sex tape vixen):

ritaora: "lil baby latex #bangbang."

So the big question remains - which beauty rocked the hotter look?

This is a rare one for Kardashian - usually her unique and classic outfits always outshine. Come on Yeezy, get your act together!

FYI - the 24-year-old "How We Do (Party)" superstar moved-on to Calvin Harris after her short-lived romantic "fling" with Rob. She's currently single. Do readers still think they could make a cute couple?
