Jimmy Kimmel, Kristen Bell, and more guest-starred in Hacks season 4 episode 5
1) Kristen Bell as herself

Kristen Bell appeared as herself in episode 5, titled Clickable Face. Deborah pretended to have a chance encounter with Bell at the grocery store and invited her to her late-night show in a desperate attempt to boost the ratings of the show. Bell agreed to appear on the show next week, and that is the only scene she had in the entire episode.
Kristen Bell is widely known as the narrator of the teen TV show, Gossip Girl, after she had her breakthrough as the title character in the series, Veronica Mars. She has voiced Princess Anna in Disney's Frozen film series and is the lead character in the Netflix romance drama series, Nobody Wants This.
2) Jimmy Kimmel as himself

Jimmy Kimmel played an exaggerated version of himself in episode 5. In the episode, he ambushed Deborah in the parking lot of the network studio and confronted her about booking Kristen Bell for her late-night show because he is more deserving of it.
Jimmy Kimmel has been serving as the host and executive producer of the late-night talk show Jimmy Kimmel Live! since 2003. Notably, he has also hosted the Academy Awards four times and the Primetime Emmy Awards three times.

3) Antoni Porowski as himself

Antoni Porowski is a Canadian TV personality and chef who appears as himself in episode 5. He appeared during a cooking segment on Deborah's show and was offended when the show host's hair extension got into the jam they were making. Later in the episode, Deborah takes Antoni to dinner, where they encounter Ava on a date with a polyamorous couple.
Porowski pursued a career in acting before moving higher up the hierarchy in the restaurant industry due to his interest in cooking. Since 2017, he has been the food and wine expert in the Netflix revival of Queer Eye. He owns the restaurant The Village Den in New York City's West Village and also deals in vintage furniture.
4) Julianne Nicholson as Dance Mom

Julianne Nicholson portrays Dance Mom, who is a TikTok dance influencer mom. Deborah and Ava initially turned down the idea of bringing Dance Mom to the show but eventually brought her on as a last-ditch effort to keep the show's ratings from falling further.
Nicholson previously worked with Jean Smart in the HBO miniseries Mare of Easttown. While Smart was nominated for an Emmy, Nicolson won one for her supporting performance. One of Nicholson's most recent projects is the popular Hulu series Paradise.
