Jason Derulo is over speaking about ex Jordin Sparks but the "Talk Dirty" singer still managed to throw a diss at the "American Idol" alum.

In an interview with In Touch Magazine, per Celebrity Dirty Laundry, he hinted that Jordin Sparks used him in order to advance her career after their split.

"I only have a problem when people air their dirty laundry in their music when it is used as a marketing tool," he said.

When he was asked by the magazine whether it's harder to be in a relationship when under the spotlight, Jason Derulo replied, "You have to be a little more careful because you never know when someone is using you."

Jason Derulo and Jordin Sparks split in September 2014 after dating for three years. Later, the "American Idol" released a mix tape which was supposedly a diss toward her ex.

Back in January, Jordin Sparks was interviewed on the Wendy Williams show where she weighed in on the split from Jason Derulo.

When the host asked her how she's doing, she replied: "I'm good, really no really, I'm good. I know you think that I'm not good but really, I'm good."

"I'm exploring my neighborhood. I'm finding places I [where] like to eat [and] meeting new people. It's been really great," she added.

On the rumors that the Jordin Sparks and Jason Derulo split was caused by his cheating ways, the "Talk Dirty" singer said, "I actually don't want to comment on that."

Jason Derulo and Jordin Sparks have actually aired their dirty laundry before the public before regarding the BMW he supposedly gifted her. The "American Idol" alum had said that he can get back the BMW after their split.

But in January, Jason Derulo posted on Instagram a receipt proving that the BMW was a leased vehicle. He captioned the image: "Women Lie, Men Lie, Numbers Don't Lie! #WhyLease#BreakfastClub."
