Finneas & Billie Eilish Have Their Own Secret Sibling Language!

Finneas is opening up about his close relationship with his little sister Billie Eilish!

The 22-year-old musician and producer recently shared that the two siblings have their own language, and it’s very simple.

“We give each other looks and the look conveys everything that we’re feeling,” he told Radio.com. “Sometimes one of us will be sitting somewhere minding our own business, and the other person will jerk their body as close to, but not touching your body, as humanly possible. And dead silent, like never any noise.”

Finneas also opened up about the rumors that he’s working with Taylor Swift.

“People were like, ‘he’s collaborating with Taylor Swift’ and I was like, ‘I am?’ I think she’s wonderful. Her songwriting has inspired me for years,” he dished. “I usually don’t like to annoy people in asking to work with them. If she wants to make some stuff I’m sure I’ll find out, and then we’ll make some stuff together.”
