'Talk Dirty' sensation Jason Derulo has revealed that while he isn't engaged to girlfriend Jordin Sparks just yet, he thinks it will happen at the right time and isn't putting that kind of pressure on their relationship. 

The hitmaker told Access Hollywood Live that planning for the future makes things a little tense so they're just taking their romance one step at a time: 

"We're not engaged yet, not yet. When the time is right and the stars are aligned perfectly [I'll propose]."

"I always have to tell myself to not allow [speculation] to interfere in the beauty that we have, and I hope that she knows that as well."

Last autumn, Derulo admitted that Sparks had a hot head, but that he was able to control his temper more effectively: "I think I'm the cool head. In our relationship. Outside of our relationship I'm not a cool head at all. I got a bad temper!"
