Singer Jordin Sparks has revealed that her boyfriend Jason Derulo wrote his new single, 'The Other Side', about her and when she hears it on the radio she can't stop herself from grinning.

During a recent interview with Parade magazine, the beauty confessed that Derulo penned the track when he was thinking about her and she loves the romance of it:

"When 'The Other Side' comes on, I get this big, cheesy grin on my face. I know he was thinking about me when he wrote it. We love being able to support each other in what we do."

Earlier this week, Derulo joked that Sparks' favourite part of his body is his stomach: "My heart, my smile. Oh, and my abs! She loves my abs." Writing on her official Twitter page yesterday (June 20), Sparks told her followers that she enjoyed a lovely break with her beau in Europe: "I had a blast w/ @jasonderulo in London, Munich & Mallorca! It's nice to be back home! Wait...where am I? #jetlag #forgetthetimezones."
