Miranda Lambert Smolders, Exposes Bra in Lace-Up Shirt at iHeartCountry Festival 2016

Only Prettier! Miranda Lambert hit the 2016 iHeartCountry Festival in Austin, Texas, Saturday, April 30, looking smoking hot in a cleavage-baring top.

The "Mama's Broken Heart" singer, 32, walked the red carpet at the Frank Erwin Center in a form-fitting, deep V-neck, lace-up shirt tucked into a belted pair of black jeans. Lambert added a sexy element to her look by exposing her black bra in the stylish netted top, and left her blonde tresses parted neatly down the side in loose beachy waves.

Lambert performed at the star-studded show alongside other country standouts, including Brett Eldredge, Zac Brown Band, Keith Urban, Lee Brice, Cole Swindell and many more. 

Missing in action were her current boyfriend, Anderson East, and her ex-husband, Blake Shelton.

That same night, Shelton hit the Radio Disney Music Awards in L.A., with his girlfriend, Gwen Stefani. The Voice costars were adorably affectionate at the event, where Stefani accepted the 2016 Ardy Hero Award for her philanthropic contributions. Joining both Stefani and the "Came Here to Forget" crooner, 39, was their fellow Voice coach Pharrell Williams, who praised the No Doubt singer as "not only someone I work with, recorded with, who I know, and what my brother, Blake Shelton, knows, truly has a heart of gold."

Stefani's rep broke the news to Us Weekly last November that she and Shelton were an item. Us Weekly also exclusively revealed the news of Lambert's relationship with East. In subsequent interviews, both parties have opened up about how they've moved on since their divorce last summer.

"This is what it is now, and we’re moving forward. We don’t need all the opinions," Lambert told Cosmopolitan in its January 2016 cover story. "We just need y’all to be supportive, and nobody pick a side — because there ain’t a side."
