The 56th annual Country Music Association Awards took place in Nashville, Tennessee on Wednesday.
Carrie Underwood, Katy Perry, and Jessica Chastain were among those who walked the red carpet.
Many of the stars opted to wear shades of blue for the occasion. See all the photos here.
Miranda Lambert looked gorgeous on the red carpet in a vintage Mugler gown.
The "Mama's Broken Heart" singer kicked off the event with a moving tribute to the late Loretta Lynn, with the help of Reba McEntire and Carrie Underwood.
Carrie Underwood chose an off-the-shoulder blue number for the occasion.
The singer was up for three nominations but sadly went home empty-handed.
Underwood also posed with her other half, former professional hockey player, Mike Fisher.
Fisher wore a dark navy suit that perfectly complimented Underwood's gray-blue gown. The country singer has been married to the sports star since 2010.
Katy Perry made an appearance, rocking double denim in a corset top and wide-leg jeans.
The pop icon was in attendance to make her CMAs debut alongside Thomas Rhett. They took the stage during the ceremony to perform their new duet, "Where We Started," which comes from Rhett's album of the same name.
Jessica Chastain made an appearance in a shimmery black and blue number.
The Oscar-winning star added some sparkle to the carpet in the embellished Gucci dress.
She then had some fun while posing with her "George and Tammy" costar, Michael Shannon.
The pair star in the upcoming Showtime country music miniseries about the romance between famed country musicians George Jones and Tammy Wynette. They were also there to present the entertainer of the year award.
Kelsea Ballerini hit the red carpet in the same bright blue Balenciaga dress Kim Kardashian wore earlier this year.
The bombshell gown was worn by Kardashian to Vanity Fair's Oscars afterparty in March.
Country legend Reba McEntire clearly got the memo as she also went for a striking blue gown.
McEntire opted for a figure-hugging velvet blue dress.
Lainey Wilson, the most nominated artist of the night, wore a golden two-piece suit.
The rising star was all smiles ahead of the ceremony. She ended up taking home two major wins, including new artist of the year and female vocalist of the year.
Lionel Richie turned up with his longtime partner Lisa Parigi.
While the "American Idol" star wore a leather jacket, Parigi — who is 40 years younger than her beau — opted for a crushed velvet blue jumpsuit.
Thomas Rhett performed his new duet with Katy Perry on stage during the ceremony and was joined on the red carpet by his wife, Lauren Akins.
While Rhett chose to don a dark blue suit for the occasion, his wife wore a shimmery green dress.
Hosts for the evening, Luke Bryan and Peyton Manning, looked dressed to impress in black suits and bowties.
Before the ceremony kicked off, the "Knockin' Boots" singer and former Colts quarterback posed for the cameras.
Reyna Roberts rocked a red lace see-through one-piece that matched her signature red hair.
Roberts finished the look with a leather cowboy hat.
Little Big Town turned up together, hoping to take home vocal group of the year.
Karen Fairchild and Kimberly Schlapman opted for floor-length gowns while Jimi Westbrook and Philip Sweet opted for dark suits.
Chris Stapleton and his wife Morgane Stapleton matched in all-black.
Stapleton was the second most nominated artist of the night with five nods and walked away with male vocalist of the year.
