Just when you thought there weren't any records left that Miranda Lambert hadn't broken, she takes that 'Gunpowder and Lead' to another.

The recent Grammy winner opened her Revolution Continues tour at Billy Bob's Texas in Ft. Worth this past weekend with sold-out shows Friday (February 18) and Saturday (February 19). This makes Miranda the first artist to fill the venue in back-to-back shows in the history of Billy Bob's.

In particular, Friday night's performance was special for Miranda, as she made an emotional dedication to her grandmother, who passed away less than a week before, before singing 'The House That Built Me.'

Tickets for the shows, which include openers Justin Moore and Josh Kelley, also sold out in a record 30 minutes when they went on sale last December.

"We at Billy Bob's Texas couldn't be happier with Miranda Lambert," Bill Bob's entertainment director Robert Gallagher says. "She was the only female artist to sell out our venue in 2010 and nearly 6000 fans per night came out last Friday and Saturday to give us the first back-to-back sellouts in our 30 year history."

Miranda's next stop on the Revolution Continues tour is Thursday (February 24) in St. Louis, Mo., followed by Evansville, Ind. Friday (February 25) and Cedar Falls, Iowa Sunday (February 26). Get details here.
