For the last time, LeAnn Rimes wants you to know that she is not engaged. "It's insanity!" she told The Tennessean before the CMAs Wednesday in Nashville.

Referring to E!'s report that Eddie Cibrian popped the question, Rimes, 28, said, "I don’t know how many times I have to say it. I say 'no' and people think we are and I’m just not admitting it."

She initially ignored the report, but her mom started calling her "thinking we’re engaged and I didn't tell her," said the singer. "It was like, 'I’ve had it.'"

Rimes -- who presented the single of the year to Lady Antebellum for "Need You Now" at Wednesday's awards show -- is preparing to spend her holidays with her man and his two children.

They'll celebrate Thanksgiving with both his and her parents at her parents' home in Dallas, she told

Keeping them entertained: The Dallas Cowboys game, "which I’m kinda sad to say we are going to, but I have to support my Cowboys, even though they aren’t doing so well right now," she told Us.

"For Christmas, we will be at home at our house with all the family coming to us."

Are there any traditions she and Cibrian, 38, are starting?

"Not really," she told Us. "He has been introducing me to the kid tradition. I’ve never had kids running around on Christmas morning."

It's exciting, she added.

"I'm one of those people that wakes up on Christmas at 5:30 -- I’ll probably be up before them!" she said, referring to Cibrian's sons. "I usually am up, getting coffee ready, breakfast ready. It’s fun to have kids around -- it’s completely different."
