Meghan Trainor and her son Riley are an adorable team!

On Monday, the “All About That Bass” singer shared adorable photographs to Instagram of the two spruced up in zoo-themed Halloween outfits to celebrate the creepy season.

Wearing an animal handler outfit, Trainor, 28, can be seen holding her 20-month-old son, who donned a lion ensemble, in her arms.

One image shows the baby — whom she shares with husband Daryl Sabara — playfully covering his head with a pumpkin trick-or-treat container while he grins for the camera in the other pictures.

“My little 🦁🧡,” Trainor basically wrote in the caption.

Earlier this month, Riley and Sabara, 30, joined the singer for her performance in New York City after she appeared on Today to talk about her new album, Takin’ It Back.

During the chat, Trainor noticed that “everything is significantly more important” since becoming a mother.

“Each song means more. I think of him when he’s 10 years old, he’s going to hear these songs. And I want him to be glad,” Trainor said of her son at the time.

Trainor also celebrates motherhood on one of the album’s tracks, “Superwoman.”

“There’s a special song on there called ‘Superwoman’ for all my mamas — all my working mamas, as well,” she shared.

“There’s super important songs on this album that’s my entire heart.” Trainor said son Riley makes her want to develop their family.

“It’s the greatest thing in the entire world,” she said as she saw Riley wearing a pair of giant headphones in the group.

“I take a gander at him and I’m like, ‘Goodness, I really want three more,’ you know? You simply want a greater amount of him.”
