f(x) member Sulli is becoming a hot topic because of her weird eating habit.

Recently on an online community, pictures were posted with the title, "Sulli's weird habit".

In the photos, Sulli seems to be sticking her tongue all the way out before she eats the ice cream and spicy rice cake.

In addition, Sulli does not seem to care about the camera going around and continues to stick her tongue out, showing her odd habit.

Internet users who saw the photos commented, "It's only cute because it's Sully, it won't work for anyone else," "She looks cute when she's eating" and "She eats like a child."

On another note, Sulli will be starring with SHINee's Minho in SBS's "To The Beautiful You," which will begin airing in August.
