Bella Noche Ruffalo, born on April 12, 2005, is Mark and Sunrise's second child. In 2022, she attended the "She-Hulk" premiere with her dad and older brother and "The Adam Project" premiere with both of her parents (pictured above). Like her older brother, Bella has had a cameo in one of her father's more famous movies: she appears in a crowd scene in "Thor: Ragnarok."
On her 18th birthday, her mom posted a tribute on Instagram, writing, "Happy 18th birthday to @belladogood. The day of your birth was one of the most magical days of my life and you have been magical ever since. We love you and are so proud of you. You have lived twice your age, and have done it style. #Wisdom." Mark added on his page, "You live your life like a comet across the sky—burning bright and beautiful. Keep going kid. So proud of you and who you are as you begin your adulthood. Xoxo."
