Abby Newman is a fictional character from the American CBS soap opera The Young and the Restless. The character was introduced on November 13, 2000, as the daughter of Ashley Abbott (Eileen Davidson) and Victor Newman (Eric Braeden). The role was portrayed by Darcy Rose Byrnes as a child until 2008, when the character was rapidly aged to a teenager, with Hayley Erin assuming the role the following year. In 2010, the character was rapidly aged again to an adult, with Marcy Rylan cast as Erin's replacement.

Abby was conceived when Ashley Abbott, desperate to have Victor Newman's child to replace the one whom she aborted years prior, stole his sperm from Diane Jenkins, who had obtained the sample illegally from a fertility lab. Ashley then secretly inseminated herself, and Abigail, "Abby" for short, was born on November 13, 2000. Abby believed her father was Brad Carlton, and was consequently given his last name. When Ashley had cancer, she recorded a video message for Abby to see when was older, and revealed Victor was her biological father. Ashley survived her cancer, but Abby saw the video without her mother's knowledge, and ran to Victor. After the truth came out, she changed her name to Abigail Carlton Newman. In 2008, Abby's birth year was revised to 1994 when she was said to be 14 years old in December 2008. With the role being recast in 2010, Abby's birth year is revised to 1988 when she is aged to 21.  Rylan was initially afraid that Abby was very similar to Lizzie Spaulding as they were both wealthy rich heiresses who caused trouble. Rylan embraces typecast and stated that as an actor, it is good to be seen as someone who can play "good, bad, and the in-between." Rylan's Abby first appears in May 2010, promoting herself as an animal rights activist. She garners the nickname, 'The Naked Heiress' when she flashes photographers in the lobby of Jabot Cosmetics.  Rylan states that Abby is a member of both the Newmans and the Abbotts and "Abby is a little more half-and-half." Marcy Rylan believes that Abby is such a rebel because she needs attention to feel like she matters to those around her. Abby's reality-TV star personality leads many to believe that Abby is the next Paris Hilton.  After a short departure, Abby returns to Genoa City in 2013. Rylan felt that she was "more mature" and said, "For the first time, Abby is feeling a little embarrassed about her previous choices [...] She's trying really hard to be a better person...and figure out where she fits if she's not running around naked."Answer this question using a quote from the following article:
