During early childhood Felicity's family performed in amateur theatre; both her mother, father, aunt, uncle and grandparents all performed in various theatre productions at Fairfield Players, with her mother Leena co-writing and directing a play based on the history of Fairfield City.

She has appeared in over 30 television and print ad campaigns including Triumph Bra's, Mercedes, Mazda, and Seiko watches to name a few.

Felicity was trained (to paint in oils) by her grandfather: Veikko Malinen, founder of the Finnish Art Society in Kotka, Finland.

Her mother Marja-Leena Malienen was an entomologist, and retired to become a full-time artist, painting predominantly land and seascapes.

In 2008 Mason held a one night only art exhibition titled "The Election Show"[15] at a private venue in Soho, NYC.

In 2021 Felicity is a contributing editor and host for NftyGuide, a site that covers NFTs in the Art and Collectables market.
