Bella Noche Ruffalo is a daughter and middle child of Mark Ruffalo and Sunrise Coigney. She has already made an acting debut by having a cameo role in Thor: Ragnarok.
Bella is very close with Mark and often accompanies him to various events. Thus, the father and the daughter appeared at 2015 MTV Movie Awards wearing matching tuxedos. And in 2019, Bella and other family members supported the actor at Avengers: Endgame premiere.
When Mark got a Golden Globe in February 2021, Bella and her brother Keen hurried up to congratulate their dad and crashed his Zoom acceptance speech.
A curious fact: in 2015, Bella donated her long hair to cancer patients.
