Jonas said one of the most romantic gestures by any of his girlfriends has been a surprise picnic of his favourite childhood delicacies, reported Female First.
"An old girlfriend once surprised me with a picnic of my favourite childhood foods. That was pretty romantic. I'm a total foodie - whatever city I'm in I try to seek out a cool place to go.
"The biggest thing is finding someone who can travel. The most romantic gesture I've made is to fly to someone, just to fly straight back with them, as I didn't have time to share the same city," Jonas said.
