Rapper Fabolous 'Dumps' Pregnant Girlfriend Emily Bustamante? Instagram Groupie Cheating Scandal, Crystal Nicole 'Hook-Up' At Floyd Mayweather Fight Exposed [PHOTOS]

Rapper Fabolous and longtime girlfriend Emily Bustamante are allegedly expecting their second child together. But now rumors suggest that the "Ghetto" superstar has been cheating on his "Love & Hip-Hop" muse with a sexy Instagram groupie, and he recently dumped Bustamante to be with this younger chick!

According to the seedy gossip webloid MediaTakeOut.com, Fabolous was caught flirting with a woman named on Crystal Nicole the popular social networking site. After some shady online stalking, MTO discovered that "[Nicole] and Fabolous would post similar pics and always seem to go to the same events." Earlier this month, both shared the SAME snapshot from Las Vegas' highly-anticipated "Battle of the Century" between Floyd Mayweather and Manny Pacquiao at MGM Grand:

myfabolouslife: "HUSTLE + MUSCLE = SUCCESS. Congrats to da homie @floydmayweather & TMT!!! #Undefeated."

Also notice that Nicole continues posting several images on her feed, but no pics show who she's actually hanging-out with...

Now MTO assumes that Fabolous dumped the VH1 bombshell for this sexy "side chick." Apparently, Nicole has since deleted her official account, but view more photographic "proof" here:

The Brooklyn emcee began dating Bustamante in 2001, and they welcomed their first son named Johan Jackson in 2008. Bustamante continues hyping her current pregnancy on Instagram, but hasn't shared any photos regarding her baby daddy in over two months. She recently posted this rather cryptic post:

emilyb_: "<3."

Do MstarsNews readers truly believe that Fabolous left his pregnant sweetheart for another "more exciting" flame? Nicole is very pretty! Here's what some other fans are already saying:

amisa: "maybe Emily will finally be a woman about hers and move on which she should've done a long time ago with his disrespectful azz."

CC: "Made a whole story about someone in his entourage lol."

Ashanti: "Emily is weak, insecure and silly. I think a younger, cuter, and more intelligent pretty black girl is perfect for Fab. Sorry. But he's not married anyway.

skinnygirluver: "She's okay but I'm not leaving a pregnant Emily for her."

MILDLY_AMUSED: "Not surprised, I guess Emily will understand that he never claimed her, he's not loyal. Move on and find someone who's proud to be around you and your kids and show you off."

So, even if Fabolous is NOT cheating, should Bustamante still move-on?
