It's official: Penélope Cruz is on Instagram, and her debut post is extremely touching. The star shared her first 'gram today, which features an 8-year-old boy named Lucas who beat leukemia. In the video, he announces Cruz's arrival to Instagram and talks about the documentary that she is working on related to the charity Uno Entre Cien Mil, which fights against child leukemia (the actress is an ambassador)—Lucas will also make an appearance in the film.

Cruz captioned the sweet post in both Spanish and English. "Lucas is without a doubt @unoentrecienmil Not only for beating leuchemia after fighting it for several years but also for how priviledge he makes you feel while listening to wise words and his amazing story," she wrote. "Lots of love and hope in the beginning of my new adventure as director of the documentary #unoentrecienmil A documentary about children's leuchemia. Charity bracelet @viceroy." Watch the clip here:
