Darcy Rose Byrnes' run as Abby Newman on both The Young and the Restless and The Bold and the Beautiful came to an end in June 2008 when Noah Newman was aged to a teenager, and Abby's character was soon to follow. In December 2008, it was announced that Erin had been cast to portray a teenaged version of the character.[3][4] In March 2010, it was announced that the character had been rapidly aged again to an adult, with Marcy Rylan scheduled to join the cast. Erin made her final appearance on April 14, with Rylan's debut on May 18, 2010.[5]
Ugh! I was like Ugh literally that is what I said! It was so emotional and I was upset. I gave him a hard time for leaving me. (Laughs) I took it personally. He's my on-screen dad! But it made for a great storyline and there was a lot of great material for all of us. So I guess, that is kind of the bright side … if there is one? But Michael is dearly missed. Michael is awesome!
In 2019, Erin played Taylor Hotchkiss, one of the main characters in the Freeform series Pretty Little Liars: The Perfectionists.[9] Erin made her feature film debut opposite Sonya Walger in the 2023 horror-thriller film New Life.[10] In September 2023, it was announced Erin would return to The Young and the Restless in the role of Claire Grace.[11]
