Justin Bieber is lending his likeness to some new merch that benefits a very good cause: helping animals affected by the recent California wildfires.

On Tuesday, the 24-year-old singer tweeted photos of some new T-shirts emblazoned with his image, announcing the shirts are a joint venture with fashion house xkarla. A portion of the proceeds from sales of the shirts will be donated to the humane society, he writes, to help “animals hurt and displaced in the fires.”

According to some Instagram posts from xkarla, T-shirts in the “Meta” collection include a shirt featuring a pic of the Biebs taking off a white shirt, and another that features his face in profile.

The T-shirts, which cost $40, can be purchased from xkarla, and are only available for one week. “Exclusive images of Justin from our campaign, in the shirt and on the shirt created for him,” notes the brand’s website; the shirts are available in both a standard T-shirt and the shorter “Baby” T-shirt.
