For her birthday this year, Red Velvet's Seulgi prepared a special treat for fans!

The idol, who celebrated her 25th birthday on February 10, took to Red Velvet's official Instagram account to share a pair of adorable baby photos of herself. 

"Thank you so much, ReVeluv," she wrote in the post. "We're in the middle of our American tour, but I am still paying attention to what's going on in Korea. I've gotten birthday messages from so many people that I don't know what to do with myself. I can healthfully and happily do the tour thanks to the energy these messages gave me! ReVeluv around the world, I love you. [Here are pictures of] baby Seulgi's birthday parties and grown-up Seulgi's heart."

In the images, she is seen celebrating her birthday at three different ages. In one, toddler Seulgi is celebrating her birthday surrounded by a table full of food, while in another, preschool-aged Seulgi is wearing a party hat with classmates' names scribbled all over it. The final picture shows Seulgi in present-day, taking a set of finger-heart selfies for her fans.

Meanwhile, Red Velvet is touring North America through February 17.
