Caitlyn Jenner was reportedly unhappy when she learned that her son Brandon was using her to promote a new series on UnchainedTV.

According to TMZ, Brandon Jenner has been allegedly using Caitlyn's name to promote "At Home With The Jenners" without her blessing.

The 74-year-old media personality was featured in a family dinner scene with David Foster on Brandon's show.

Aside from finding out that she's being used for the show's promotions, she's not happy that she was actually filmed for the show.

Because of the issue, the former Olympic-winning decathlete's attorneys reportedly reached out to the show's production company, threatening legal action if Caitlyn's cameo appearance was not removed from the show.

Caitlyn has since been scrubbed from all of her unapproved future appearances on the show, the outlet reported. The previous episodes she already appeared in were altered to delete her presence.

While she wished her son nothing but the best, she was also reportedly furious about how the show was handled recklessly just to sell it.

Brandon is one of the former Olympian's children, alongside Burt, Cassandra, Brody, Kendall and Kylie.

Caitlyn has six children with three different ex-spouses: Burt and Cassandra with Chrystie Scott, Brandon and Brody with Linda Thompson, and Kendall and Kylie with Kris Jenner.

"At Home With The Jenners" is a new UnchainedTV series, where Brandon and Cayley Jenner invite viewers into an inside look at their Malibu home and plant-based lifestyle.

The couple married in January 2020 and welcomed their twins, Bo and Sam, that same year. The twins, as well as Brandon's daughter, Eva James, with ex-wife Leah James, will also make appearances on the show, per People.

Their 14 pets will also make cameos in the "Forks Over Knives"-inspired series.

Meanwhile, Caitlyn is reportedly in the middle of renewing her contract with Fox and wants to keep working as a Fox News contributor.

TMZ sources said Caitlyn could be in a serious breach of contract if she joined a reality show from a different network.
