Rockin' Out!

Calling the experience of watching Guns 'N Roses "one of the top 5 nights of my entire life," Carrie Underwood captioned the video, "After the last show of our tour last night me and the band flew out to Vegas [Caesars Palace] for a [Guns N' Roses] show. It. Was. Incredible. I’m talking 3 hours worth of incredible!" Stating she could already tell her body would be wrecked the following day, she added, "I know I’m going to be hurting tomorrow because I rocked out so hard, but it was worth it. Thanks to all who made this night happen for me and thanks to my band for pretending I wasn’t embarrassing you all with my antics!"

That's a Wrap!

The country star also shared more videos of the concert on her Instagram story over the weekend. Carrie Underwood wrapped up her "Cry Pretty Tour 360" on Thursday at Little Caesars Arena in Detroit. Meanwhile, Guns 'N Roses also finished up their "Not In This Lifetime" Tour at the Colosseum at Caesars Palace in Las Vegas on Friday and Saturday night. During the band's Friday night show, Axl Rose slipped and fell while performing "Knockin' On Heaven's Door." It took a while for the frontman to recover but he turned out to be fine. Axl Rose wiped down the stage floor and went right back to performing.

Halloween!

Carrie Underwood ended her tour by sharing a heartfelt message to fans. Posting a video on Instagram, the "Cry Pretty" singer thanked everyone who came out to support their shows. She held back tears while she described how special the tour was to her. "It's one to remember and you guys made it happen," Carrie Underwood said. Her sons -- Isaiah Michael, who's 4 years old, and Jacob Bryan, 9 months -- as well as her husband, NFL star Mike Fisher, were there to cheer the star on during her last show.

They made it a special one too, with Carrie Underwood and family dressing up in adorable costumes and posing for a group photo. The singer shared the snap with fans showing herself dressed in a colorful Care Bears onesie. Mike Fisher channeled Buck Daniels from "Saturday Night Live" by wearing a mullet wig, giant mustache, a baseball cap and sunglasses. He showed his support for his wife by wearing an official Carrie Underwood concert tee. Their oldest son won the best look of the night by painting his face green and posing as The Grinch. His little brother dressed as Grinch's adorable canine sidekick, Max. "Hope everyone had a good #Halloween ! Lots of love from Cheer Bear, The Grinch, Max and Buck Daniels..." Carrie Underwood wrote.

11-Years Down!

Carrie Underwood and Mike Fisher are so in love that they recently celebrated the anniversary of when they met 11 years ago. The famous couple got all dressed up and left the kids at home for a night out on the down. They enjoyed dinner and took a sweet snap together to commemorate the very first night they laid eyes on each other. Posting the couples photo to her social media, Carrie Underwood wrote, "11 years ago yesterday, I met the love of my life...patient, kind, the best dad, handsome, of course! Someone who accepts me and all my flaws...the same as me in many ways...opposite in some. But he is my match. The iron to sharpen me....tonight we celebrated at @delposto . A rare night out with amazing food and even more amazing company and conversation. Here’s to so many more years together. Love you, babe!"
