Last week, Nick Jonas called in to On Air with Ryan Seacrest to give Ryan Seacrest some Valentine's Day tips and revealed he once courted someone with an original love song. Like a real friend, he offered to ghostwrite a romantic track to help Ryan score some V-Day points.

"So here's my thought. Why don't I write you a song that you can say you wrote," Nick suggested, "and we'll go from there."

The pop singer made good on his promise by FaceTiming Ryan on Valentine's Day morning and performing a Valentine's Day rework of his smash single "Jealous." With the mere accompaniment of his acoustic guitar, Nick delivered the new lyrics in the beat of the 2014 hit.

Nick will be spending Valentine's Day at the Bee Gees tribute concert at the Microsoft Theater in Downtown Los Angeles. The Grammy Salute will also see performances by Tori Kelly, John Legend, Little Big Town, Demi Lovato, Pentatonix, Keith Urban, and Bee Gees founding member Barry Gibb.
