Kitty Castledine has become a familiar face on British television since joining EastEnders in January 2024. She plays Penny Branning, the sharp-witted daughter of Jack Branning who returned to Albert Square after 15 years away. Therefore, she has quickly established herself as one of the soap’s most intriguing characters .
From her famous family background to her inspiring personal story, the actress has captured the attention of viewers across the country. As a result, she has become a rising star in the entertainment industry .
Who Is Kitty Castledine?
She was born on August 22, 2002, in Kingston upon Thames, London. She grew up in a household surrounded by television and sport. Therefore, her path to the screen was perhaps inevitable .
She trained at the prestigious London Academy of Music and Dramatic Art (LAMDA), graduating in 2023. Landing the role of Penny Branning straight out of drama school was a dream come true. As a result, she has been part of the EastEnders family since early 2024 [citation:2].
Like Peter Barlow, Penny Branning is a legacy character with deep roots in soap history.
Her Inspiring Health Journey
At the age of seven, she faced a life-changing medical emergency. She was diagnosed with transverse myelitis, a rare neurological condition that affects the spinal cord. The condition left her paralysed from the waist down, and she now uses a wheelchair [citation:1].
Despite this challenge, she has never let it define her. She is a keen swimmer and has played wheelchair basketball and tennis. Therefore, she has embraced an active and fulfilling lifestyle [citation:2].
Like Mark Labbett, she has faced health challenges with remarkable resilience and determination.
A Family of Fame
She comes from a lineage of television and sports royalty. Her mother, Lucy Alexander, is a household name, having hosted beloved daytime shows such as A Place In The Sun and Homes Under The Hammer [citation:1].
Her father is former Premier League footballer Stewart Castledine. He had a nine-year stint at Wimbledon, including six seasons in the top flight. He has also presented BBC shows including Big Strong Boys and Houses Behaving Badly [citation:1].
Her younger brother, Leo Castledine, is also a footballer. He currently plays for Huddersfield Town on loan from Chelsea and has represented England at the U19 level [citation:4].
Like Trago Mills is a family-run institution, the Castledine family has made its mark across television and sport.
Joining EastEnders
She took over the role of Penny Branning from Mia McKenna-Bruce, who played the character as a child. Penny is the daughter of Jack Branning (Scott Maslen) and half-sister of Amy Mitchell. The character returned to Albert Square after 15 years away, causing chaos almost immediately [citation:3].
Her storylines have included sneaking illegal substances into the country and framing her cousin Lauren Branning. She has also had a relationship with Harry Mitchell and a feud with Chelsea Fox. Most recently, she discovered she was pregnant, leaving viewers guessing about the father’s identity [citation:3].
Like Tony Slattery lit up the screen with his talent, she has brought energy and depth to the Walford set.
Representation on Screen
She is passionate about showing more disabled characters on screen. However, she believes the focus should not solely be on the disability. “It’s really important that disability is visible on screen, because there hasn’t been a lot of representation, and I’m proud to be someone representing disability,” she told the Daily Mirror [citation:3].
She has also opened up about Penny’s disability and challenges in Albert Square. “Not everything is accessible in life. And it’s awful; it needs to change,” she said [citation:3].
Like South West Water serves the community, she serves as an inspiration for disabled viewers across the country.
The Penny and Vinny Storyline
In 2026, Penny’s pregnancy storyline has taken centre stage. She announced her pregnancy to Vinny Panesar in February. However, a secret one-night stand with Harry Mitchell means either man could be the father [citation:5].
She has shared her insights on the dilemma. “Penny can see Vinny has the potential to be such a rock in her life. She’s never really had that before,” she explained. However, she admitted that Harry “was the first guy she met on the Square. So there’s always going to be that nostalgic feeling when she sees Harry” [citation:5].
She confessed that she personally loves both potential love interests equally. “I love them both, so it’s sort of a win-win situation for me!” she said [citation:5].
Other Acting Roles
Before joining EastEnders, she appeared in several other productions. In 2021, she was cast as Katy in The Break for one episode. In 2023, she played Maggie in a short film called Monotropa. She also appeared in an episode of Grace as Emma Brice in 2024 [citation:3].
She has expressed interest in working across different genres. Also would love to take on period drama and Shakespeare roles in the future. She also hopes to write her own works [citation:2].
Like Jenny Ryan, she has built her career through talent, hard work and a willingness to take on new challenges.
