2NE1's Park Bom showed off her 'special' face spray on the latest episode of 'Roommate'!

She claimed that her facial spray had the ability to shrink peoples' heads. "If you spray this, your head becomes smaller," she said. "My actor friends use it a lot."

Park Bom proceeded to spray every inch of Shin Sung Woo's face with her spray. "This is expensive," she reassured him while coating his face with her special miracle drug.

Her miscellaneous hygienic habits also drew attention around the house, including her tendency to stick blood pressure stickers behind her ears when she slept! (An eight-dimensional character, indeed.)

Meanwhile, it was a happy day for 2NE1 fans this Sunday, as they were able to see three straight hours of their girls on both 'Roommate' and this week's episode of 'Running Man'!

Check out the full 'Roommate' episode below.
