Created by head writer Sally Sussman Morina, the role was originally played by Mandy Musgrave.

In 2005 after Chelsea Benson's parents are killed in a car accident, DNA tests show that she is Georgia Reed Brady.

[4] Melvin reprised the role on September 7, 2023, as part of a memorial episode dedicated to John Aniston's Victor Kiriakis.

The truth comes out when Chelsea's illegally adoptive parents are killed in a car accident and blood tests reveal her true lineage.

Chelsea is also obsessed with older men including Patrick Lockhart, who is conveniently staying at Abby's house.

While serving her community service at the hospital, a gloved hand leaves a file for Chelsea to discover.

Thinking she is doing the right thing, Chelsea leaves the file in Shawn's cubicle for him to find while he lies unconscious from alcohol poisoning.

Bo decides that the only way to prove that Chelsea is guilty is to run the DNA test on Shawn to see if he is Claire's biological father.

The fire is actually started by Willow Stark, a former prostitute and ex-girlfriend of Shawn Brady, who is hired by EJ DiMera to break into the house.

Chelsea and the girls create posters depicting Ford as a rapist and are threatened by him on several occasions, the latest being at the Brady Pub where Nick is forced to defend her.

In November, Chelsea and Nick break into Ford's dorm to obtain proof that he is indeed the campus rapist.

After being appalled by the university's unwillingness to do anything to Ford, the girls lure him into their sorority house where Chelsea pretends to be interested in him.

Chelsea is found to be a match and is scheduled for an experimental operation to graft some of her pancreas to save Bo.

Bo's handsome and earth-friendly doctor, Dr. Daniel Jonas, (who is brought in by Victor Kiriakis) performs the surgery.

Afterwards, she begins defending Nick Fallon, her "first love," who is charged with Trent Robbins murder, and growing closer to her old flame, Max Brady, whom she kissed at New years dinner at Chez Rouge, suggesting that they may get back together.

She returns to Salem in 2023 for Victor Kiriakis' memorial, revealing she and Max have a son, Isaac.
