Britt McKillip has built a versatile career as a Canadian actress and singer, earning recognition for her work across live-action television, feature films, and an extensive array of animated voiceover roles. Born in 1991 in Canada, McKillip grew up alongside her sister, fellow actress Carly McKillip, and began pursuing acting at a young age. Her early credits included guest appearances on popular television series such as The Dead Zone and Stargate SG-1, where she demonstrated a natural aptitude for both dramatic and genre storytelling. These formative roles paved the way for a breakout performance that would define much of her early career.

McKillip is perhaps best known for her live-action portrayal of Reggie Lass on the cult-favorite television series Dead Like Me, which aired from 2003 to 2004. The show, created by Bryan Fuller, followed a group of grim reapers navigating the complexities of their afterlife duties, and McKillip’s character was the younger sister of the protagonist, George Lass, played by Ellen Muth. Her performance was praised for bringing warmth and emotional depth to the series, and she later reprised the role in the 2009 film Dead Like Me: Life After Death, which continued the story of the reapers. This dual role in both the series and its film adaptation cemented her status as a memorable figure in early 2000s television.

Beyond live-action, McKillip has amassed an impressive portfolio of voiceover work, becoming a familiar voice in children’s animation. She voiced Lola Bunny in the animated series Baby Looney Tunes, bringing a youthful energy to the beloved Looney Tunes character. She also took on the iconic role of Sabrina Spellman in Sabrina's Secret Life, a direct-to-video series that expanded the universe of the teenage witch. Her voice credits further include Amethyst van der Troll in Trollz, Cloe in the Bratz franchise, and Blueberry Muffin in Strawberry Shortcake's Berry Bitty Adventures. One of her most notable animated roles came as Princess Cadance in the long-running series My Little Pony: Friendship Is Magic, where her vocal performance endeared her to a dedicated fanbase. She also lent her voice to Princess Harumi in Ninjago, showcasing her range in action-oriented animated storytelling.

In addition to her acting career, McKillip is also a talented singer, having contributed to soundtracks for some of her projects. Her musical abilities have occasionally intersected with her voiceover work, adding another layer to her artistic identity. While she has remained relatively selective with her on-screen appearances in recent years, she continues to be active in the entertainment industry, particularly in voice acting. McKillip’s career reflects a steady dedication to her craft, from her early days on a beloved television series to her enduring presence in the world of animation, where she has brought countless characters to life for audiences of all ages.
