Jason Derulo Cheating Scandal Exposed, Instagram 'Groupie' Carmen Ortega Sexy Bikini PHOTOS: Jordin Sparks Break-Up After Reggie Bush & Kim Kardashian 'Betrayal'

Several fans once considered Jason Derulo and Jordin Sparks Hollywood's "cutest" R&B couple. That quickly changed once Derulo dumped the former "American Idol" sweetheart in September 2014 (after three years of dating). Apparently, things ended mutually - but rumors now suggest that the "Talk Dirty" singer actually cheated on Sparks with a sexy Instagram model. Introducing, Carmen Ortega:

The aspiring actress has more than 264,600 followers and counting on the popular social networking site. The bootylicious bombshell enjoys posting several sexy bikini snapshots:

carmenortega: "This suit is everything."

carmenortega: "Wonder what I was thinking? Love this shot."

carmenortega: "Take every moment in lik it's your last... La Vida."

Wonder if she's still secretly hooking-up with Derulo? Ortega was recently spotted soaking up the sun in South Beach, flaunting a skimpy thong swimsuit. Those images are currently going viral on MediaTakeOut.com. Do MstarsNews readers think she's hotter than Sparks, or did Derulo make a huge mistake?

Well, some fans are torn:

Everybodygotchoices: "She's not the cutest, but everything on her is real. No it's not toned, but that's what makes her different from all these blueprint bodies..."

blackgirl91: "A ho gonna be a ho ain't no way around it."

FЯ∑∑ ㄅㄕⅰЯⅰɬ✌️: "He shoulda hung onto Jordin."

Jay Smooth: "Not surprised he's just being a man with money and opportunities. What if Jordin was trash in bed? What if she didnt like giving head? Plus he probably just wanted to feel some new cat. Everything gets old no matter how beautiful it is."

rafffi: "I love that booty."

Apparently, NFL superstar Reggie Bush also cheated with Ortega while he was still dating reality starlet Kim Kardashian, and that's why they ultimately broke-up a few years ago. Ortega admitted to all of her "inappropriate" celebrity flings.
