Selena Gomez and Nick Jonas appear to have learnt nothing from Miley Cyrus' 'hacked photos' episode and have reportedly been  sending each other saucy emails and texts.

Although the pair have denied being an item, rumours continue to fly, with insiders now claiming they have taken to expressing their mutual longing online.

"I love your mouth and I love your smile. It totally melts me," Nick wrote to Selena, according to Star.

The magazine's mole says that the youngest Jonas Brother is besotted with the Disney starlet.

"They have inside jokes and write sexy little things - he's totally in love," the source says.

"They are addicted to e-mailing each other. That's what teenagers do!"

If Nick has cyber sex, can he still wear his promise ring?
