Who Is Sienna Bacall?

According to Braun, Sienna is no ordinary newcomer. She’s described as a Hollywood club owner with a mysterious edge, making her entrance both glamorous and shadowy.

“She runs a club in Hollywood,” Braun teased in an interview. “There’s mystery there, which I think is a really cool way to introduce a character—and very fitting for a soap.”

Her arrival ties directly into Noah Newman’s Los Angeles storyline, which also introduces new characters played by Roger Howarth and Matt Cohen (Detective Burrow).

How Sienna Fits Into the Story

Noah has been exploring a business opportunity involving his nightclub, with Sharon and Nick joining him in LA to learn more. That’s where Sienna comes in.

The speculation? She’s either partnering with the project developer—or being forced into shady dealings behind the scenes. If it’s the latter, Sienna may try to lure Noah in with promises of success, masking a much darker agenda.
