On Friday, the pregnant singer, 36, was hit by a fire truck in Texas, but doctors said both she and the baby would be fine. On Saturday, the singer said she had her car to thank for that.
"[One] thing I do know is my car saved my & my baby's life," Jewel Tweeted. "Definitely going 2 get another Cadillac SRX! It absorbed all the damage & kept me safe!"
Now, she's enjoying some R&R on doctor's orders.
"Dr said no working out," she wrote, "so I'm just going to take it easy this weekend. Just a little sore and banged up – but feeling so blessed this morning."
In January, Jewel told PEOPLE that she and husband Ty Murray (who tried to get pregnant for two years) are having a boy.
