Miranda Lambert Baits Jamey and Lets Blake ‘Off the Hook’

It's been a week Miranda Lambert will never forget. 'White Liar' has topped the country charts, her first No. 1 song ever.

"I'm so excited about everything right now -- the Grammys, and 'White Liar' is my first Top 5 -- I've never even had a chance to fight for a No. 1!" Miranda tells Chicago Country Radio US99.5.

According to Miranda, Jamey Johnson never had a fighting chance either, when she asked him to be in her video for 'White Liar.'

"I actually had a motive when I invited Jamey," Miranda jokes. "Because I knew he brings the moonshine!"

This weekend, Miranda won't be bringing boyfriend Blake Shelton to the Grammys with her. She's nominated for Best Female Country Vocal Performance for 'Dead Flowers,' and the date on her arm will be another lucky guy.

"Blake is not a big fan of award shows, so I told him he was off the hook," Miranda explains. "But my little brother is 21, and he's never been. So I invited him."

So what will the feisty Oklahoma beauty be wearing to 'Music's Biggest Night?'

"I'm wearing a dress that I'm getting made ... I only have one option, so it better fit!" she says with a laugh.

As for Blake, there's someplace else Miranda has taken him that he doesn't seem to be a fan of.

"One time I took him to Tiffany's, and I was gonna buy some earrings," Miranda recalls. "Talk about a fish out of water!"

But ... does Miranda every dream of getting that Tiffany's signature, porcelin blue box from Blake?

"You know what ... I think every girl loves a blue box -- whatever's in it," Miranda softly admits. "It's awesome."
