Disney executives are said to be fuming over the recent bout of relationship rumours surrounding Nick and Joe of The Jonas Brothers.

The pop sensations – who wear purity rings as a sign of their chastity vow – reportedly been given a ticking off for flaunting their love lives in the press.

Teen heartthrob Joe is rumoured to have been dating The Hills actress Lauren Conrad and country singer Taylor Swift, and there has been speculation over 15-year-old Nick's relationship with Hannah Montana star Miley Cyrus and reality star Kim Kardashian.

Disney bosses are apparently anxious over the stories and fear they could be hit with a crisis comparable to Miley’s recent provocative photoshoot with Vanity Fair magazine – which caused a public outcry because of the singer’s young age.

"There is a constant stream of photos, gossip and sexual innuendo about the Jonas Brothers that just isn't in keeping with their - or our – image,” an unnamed senior Disney executive tells Daily Star Sunday.

“We need to figure out how to play it all down before it explodes in our faces like it did with Miley."
