Beyonce & Kim Kardashian Unite, 'Fake' Baby Bump Advice: Jealous Rihanna Beef Explodes

Kim Kardashian's proud to bond with Beyonce over pregnancy talk. Perhaps during these baby bump convos they also gossip about common "frenemy," Rihanna!

Apparently, Queen Bey's giving Kanye West's wife some tips on how to conceal her growing baby bump from paparazzi. Such advice must be working, considering some fans now believe that Kardashian isn't even pregnant with her second child! Both Hollywood beauties find such gossip hilarious:

"Kim reached out to Beyonce and had a good laugh about it," an alleged insider tells the popular entertainment webloid HollywoodLife.com. "The Internet went wild with speculation that Beyonce faked her pregnancy too, so she knows all about it. And like Kim, Beyonce liked keeping the media guessing."

The "KUWTK" starlet isn't faking her pregnancy - she's simply trying to hide it! But why? Maybe to avoid constant media attention... like that'll ever happen!

So, what did the Destiny's Child superstar tell North West's momma to do?

"She told Kim to hide her bump using purses, bags, flowing dresses and coats to mess with the media," the source reveals.

Well, such little maneuvers are apparently working!

Meanwhile:

"Kim thinks the whole 'fake' baby bump controversy is hysterical," another HL snitch explains. "If anyone doesn't think she's pregnant they should take a look at her swollen feet and legs."

Ha.

Thankfully Jay-Z's main squeeze has someone to talk to, considering cyber drama involving fellow songstress Rihanna just won't end. Now Bey's marriage is even in jeopardy (supposedly):

But Rih has other issues to deal with - like the fact that ex-boyfriend Chris Brown might be trying to win her heart back (again). The Barbadian BadGal is Breezy's "baddest b*tch" for life, right!?
