Who Is Katie Arundel? Amanda Batula’s Childhood Best Friend and Loyal Voice on Bravo’s “In the City”

Katie Arundel is a new face joining the Bravo universe as a core cast member of In the City, the highly anticipated Summer House spinoff premiering May 19, 2026.

Described as dependable, warm, and fiercely loyal, Katie serves as one of Amanda Batula’s closest confidantes — her childhood best friend — bringing honesty, support, and the occasional tough love to the group navigating life in New York City.

Professional Background

Details about Katie Arundel’s professional life remain relatively private compared to some of her castmates.

She is based in the New York City area (Williamsburg) and maintains a low-key presence outside of her friendships in the Summer House circle.

Her Instagram (@katiearundel) offers glimpses into her personal world, but she is primarily known on the show for her strong personal connections rather than a high-profile career spotlight.

Personal Life and Friendships

Katie shares a deep, long-standing bond with Amanda Batula, having been friends since childhood.

She is one of the few people Amanda fully trusts amid the ups and downs of her separation from Kyle Cooke. Katie is also close with Danielle Olivera, creating a layered dynamic of loyalty that could lead to complications when friendships within the group are tested.

Known for her ride-or-die energy, Katie isn’t afraid to speak her mind — especially when it comes to challenging Kyle.

Her warmth and dependability make her a grounding presence, but her divided loyalties (between Amanda and Danielle) add potential for emotional and dramatic moments as the group deals with reinvention, relationships, and growing up.

Filmed in fall 2025 right after Summer House Season 10, In the City follows Katie and the rest of the cast as they shift from Hamptons summers to year-round NYC life.

Her storyline centers on friendship loyalty, offering support to Amanda during a turbulent time, and navigating the complications that arise when she’s close to multiple sides of group conflicts.

Viewers can expect Katie to deliver heartfelt advice, honest confrontations, and the kind of authentic “best friend” energy that often sparks real conversations — and occasional drama — on Bravo.
