Roche, 22, and Nelson, 23, are serious for each other though it is a new relationship, reported the Daily Mirror.
"It's early days but Jesy and Jake seem smitten with each other. They're seeing how things go. They're both always busy with work so they know it will be hard, but both of them want to make it work. They're very similar to each other and like a laugh so are well suited," a source said.
Nelson wrote against one snap, "Happy birthday to this absolute fruit cake jake_rixton aka 'James poach'. You make me laugh every day without fail! Have the best day ever, my little mate.
