Heidi Jo Mueller (* January 29, 1982 in Cincinnati, Ohio) is an American actress. She portrayed the role of Kay Bennett on the NBC daytime soap opera Passions from 2003 until 2008.


Prior to Passions, Mueller appeared alongside her father Don Mueller and her siblings on the NBC reality TV series Who Wants to Marry My Dad?.

Mueller joined Passions in 2003, the fourth actress to portray Kay (and also played Kay's ancestor Prudence Standish in a flashback).
She continued in the role when the series switched to DirecTV on September 17, 2007.

In 2007, Mueller appeared with co-star Adrian Bellani on The Tyra Banks Show for a feature in which host Tyra went through "soap opera school."

Renowned actress Juliet Mills, Mueller's costar on Passions, said of Mueller in 2007, "When she started, she had never acted and came from the reality show ... she was always very serious about the work and worked really hard to learn her lines. A soap opera is like boot camp. Now, she makes it all seem very spontaneous, and she's right there for you. It's really been lovely to see her grow as an actress."[2] Passions costar Ben Masters added that Mueller "has the ability to make the words come out of her mouth so naturally; [dialogue] comes cascading out of her. I did a whole week with her where we had all these scenes, page after page after page; it was just wonderful. It's like she's got a perfect pitch as an actress."
