Whew -- is it hot in here?

Country's hottest stars turned the heat up even higher as they walked the red carpet with their significant others, occasionally kissing for the cameras.

Carrie Underwood and husband Mike Fisher were the undisputed king and queen of the red carpet, looking like a real-life Barbie and Ken. How gorgeous is Carrie's dramatic indigo gown?!

Meanwhile, fellow knockout Kellie Pickler shared a smooch with husband Kyle Jacobs. Another hot country star duo? Kelsea Ballerini and Morgan Evans, who couldn't take their eyes off each other.

Of course, there's no need for arm candy if you're already looking incredible! Plenty of stars showed up stag and slayed: Pregnant Jessie James Decker, who usually hits the red carpet with hubby Eric Decker, strutted her stuff solo and killed it! We also loved Danielle Bradbery's daring thigh-high slit.

Take a look at all the looks in the gallery below:
