In the latest “ROSÉ “On The Ground” | Countdown to Premiere” episode of RELEASED — a series on BLACKPINK’s YouTube channel,” Rosé called Alice, and the two had a playful over-the-phone interview. During the call, Alice was asked if Rosé has any weird habits.

Rather than talking about a weird habit, Alice shared that Rosé has an “annoying habit” of clicking her knuckles.

Rosé laughed and immediately knew what Alice was talking about. Rosé explained that she has a habit of clicking her thumb.

Alice shared that when Rosé does this, it “annoys the person sitting next to her.” This habit is especially “annoying” to Alice. While Alice was talking about this, Rosé was laughing.

Rosé then shared that if she’s with someone she’s close to, she will sometimes click her thumb on purpose to “annoy” the person.
