Emily Maynard: Caught Cheating on Jef Holm, Sexting With Another Man?!

Another Bachelorette romance is on thin ice after Emily Maynard was caught cheating on fiance Jef Holm ... according to an unreliable tabloid report.

The celebrity gossip magazine reports that Emily fled a recent vacation in tears after Jef discovered her sending explicit photos and texts to another man.

We're talking seriously dirty stuff here. Allegedly. “There were texts and pictures: 'Let’s do this and that with each other,'" says a source. Yikes.

Not only that, the bad scene allegedly went down at a vacation rental where Jef Holm had taken Emily Maynard to meet his extended family.

“Jef and Emily went into a bedroom and were yelling. He said, ‘You’ve been f**king cheating on me for months!’” a source is quoted as saying.

His final words to her? "'Pack your s**t and get the f**k out.'"

Yeah. If that's true, obviously this is serious and shady on her part, but we have our doubts. Considering the source, it's a dubious claim at best.

If there's any tension between Emily Maynard and Jef, they sure weren't showing it during a lovey-dovey outing in Charlotte, N.C., yesterday.

The Bachelorette couple ran errands in her hometown, and either they were trying to not-so-subtly deny Us' cover story, or they're just that cute.

From the looks of these pics, that was likely bull$h!t ...

This isn't the first time Emily has been embroiled in scandal; she was accused of sleeping with Arie Luyendyk, Jr. right before proposing to Jef.

What do you think? Will Emily and Jef last?
