Jamie Lynn Spears and Casey Aldridge There are rumours aplenty surrounding Jamie Lynn Spears and her boyf Casey Aldridge.

Word on the street has it he's done the dirty on her.

Has the teen couple's relationship been tested to the limit?

Apparently not.

The lovebirds, who have a baby daughter, Maddie, together, claim they're still going strong - but are fed up with all the spurious gossip.

Speaking to OK! magazine, 19-year-old Casey said stories about him being unfaithful to Jamie Lynn were "not the least bit" true.

"That's news to me," he said, in response to hearsay that he'd made childhood friend Kelli Dawson pregnant.

So how does he explain the misunderstanding?

"In a small town, everybody knows everybody," he said. "But when money's involved, you find out who your friends are."

"That is just completely fabricated," Jamie Lynn added, in response to the cheat goss.

"He never had an intimate relationship with her (Kelli), so how would that be possible? Around here, that particular girl is known to make up stories."

"It hurt me to hear those things because my family has to read it," the 17-year-old went on. "It's not fair to them."

 However, Jamie Lynn did add that her rellies aren't taking the stories to heart, commenting:

"My family supports me, and they support Casey also. They read those stories and take them with a grain of salt."

And so do we... unless there's solid proof of course.
