Carrie Underwood had to break into her car in the Tennessee heat to rescue her 4-month-old son who was accidentally locked inside, according to People.

The country star told fans Saturday she had to smash a window to get in after her dogs locked themselves in the car with her baby, Isaiah.

The magazine said the singer tweeted about it afterward.

"When your dogs manage to lock themselves, all your stuff & the baby in the car & you have to break a window to get in," she wrote. " #WhatAreTheChances."

Underwood became a first-time mom in February when she and her husband, NHL player Mike Fisher, welcomed Isaiah. On July 10, the couple celebrated their fifth wedding anniversary.
