Her future remains open in a positive way, giving her the freedom to shape her life based on her own dreams, not public expectations.
Life as a Celebrity Child

On the good side, Oona has been exposed to creativity, art, culture, travel, and inspiring people through her mother’s work. She has had the privilege of growing up around strong, talented adults who show dedication, passion, and love for their craft.
On the challenging side, being connected to fame means dealing with public curiosity and the need for strong privacy. Yet Oona’s parents have handled these challenges wisely, always placing family life, emotional health, and education above everything else. Because of this careful balance, Oona has grown into someone who seems grounded and unaffected by the pressures of celebrity culture.
Future Aspirations

What matters most is that she has the support of a family that encourages her to find her own voice and follow her own dreams.
