Jason Derulo; Singer's Side Chick Admits “We Dated While He Was Still With Jordin Sparks”

Looks like the 'Talk Dirty' singer, Jason Derulo just lied! He'd denied cheating blaming Sparks for the split! Let's all shout 'Wiggle Wiggle Wiggle' because Jason Derulo's testimony of Jordin Sparks pressuring for marriage as the cause of their split may have been a lie! The singer's alleged side chick Carmen Ortega confessed to Star Magazine in a recent interview earlier this week. The model said that Derulo and herself had a one month affair while he was still with singer Jordin Sparks adding he lied their relationship wasn't real but was strictly for music business! Here is what she said: “We dated for a month,” the brunette beauty reveals. “We went out in public with friends a few times, so I assumed he didn’t have a girlfriend.” When Carmen realized that Jason was publicly dating the American Idol winner, she called things off. “I cut ties with him immediately,” she says. “He tried telling me their relationship was strictly fueled by management teams. He lied to me the entire time.” In a radio interview with Ryan Seacrest, Derulo denied cheating and then said his ex Jordin was pressuring him to get married and that's the real reason he broke things up with her-- on the phone! Ouch! Meanwhile, Jordin claims the 'Talk Dirty' singer is just talking cheap, “that's what it is, just talk” the 'Sparkle' actress told a reporter on her way to the Wendy Williams Show last week! Well, with Carmen talking dirty now, what do you think really caused the sweet Hollywood couple's shocking split?
