Despite the reveal, little Vivianne still seemed convinced that her mom is having a girl.

Jessie recently dished to E! News about her upcoming arrival, sharing that she would likely have to share the news of her baby's sex soon because Vivianne was having a bit of trouble keeping the secret.

"I'm gonna have to probably announce it soon though because Vivianne knows what it is and she keeps telling her entire class and all the teachers are coming up to me after school going, ‘Vivianne prayed for baby blank during lunch. We're so excited,'" the singer explained. "I'm like, ‘Vivianne! You are telling everybody.'"

As for her baby's name, Jessie didn't spill, but she did share a big hint.

"I'll give you a hint," she said. "My friends know I'm a really big movie buff and I named Vivianne after a movie character. She was named after Vivianne Walker in Ya Ya Sisterhood. And I love Southern names so the hint I will give you is I'm naming this baby after another Southern character from a movie. One of my favorite movies."
