Setting an example with their own love, Kevin Jonas and his wife Danielle joined the United States Postal Service to unveil the 2013 Sealed with Love stamp in New York City on Tuesday (February 5).

The eldest JoBro wore a patterned shirt with a black jacket and black pants while his lovely bride wore a black jacket and short dress, showing off her legs while she smooched her man.

Speaking with a local ABC station about their relationship, the 25-year-old musician gushed, "we're a couple after four years still rockin' in love and we're happy to be a part of it."

Put on the spot for a "Not So Newlywed Game," the happy couple revealed that their first kiss was in their parents' garage and their best Valentine's date was on the tour bus.
