Sabrina Costelana Newman

Sabrina Costelana Newman appeared from February 28 to August 5, 2008, portrayed by Raya Meddine. She was introduced as a friend of Victoria Newman (Amelia Heinle), later pursuing a romance with her father Victor Newman (Eric Braeden). Despite the character dying onscreen, Meddine reprised the role numerous times after Sabrina's death.

History
Sabrina was introduced as a friend of Victoria Newman, whom she had met while she was living in Florence. She arrived in Genoa City in February 2008 to visit Victoria after Victoria had contacted her via e-mail and instantly found herself attracted to Victoria's recently divorced father, Victor Newman, with whom she shared an interest in art. It was soon revealed to viewers that Sabrina had worked as an art curator in Florence, and that she had recently broken up with a man named Phillipe. Before she was about to leave Genoa City, she shared a kiss with Victor Newman. Their attraction soon turned into a relationship, leaving both Victor and Sabrina worried over Victoria's reaction. After learning about it, Victoria furiously confronted her friend, leaving their friendship shattered. Meanwhile, Sabrina accepted Victor's proposal to manage an art gallery that Victor was going to open up for her in Genoa City. Sabrina revealed she was pregnant, and afterward they married.

Zara Costelana, Sabrina's mother, arrived in Genoa City the day before the wedding, even though she was not invited. Victoria later explained to Nick and Phyllis that the reason mother and daughter have a strained relationship is because Zara was not a nurturing parent, preferring instead to treat Sabrina as more of a sister or friend following Mr. Costelana's assassination, rather than a daughter. Sabrina's father was a diplomat who was killed while performing his job, which shattered Sabrina and her mother's relationship.

Sabrina agreed to be in an article in the new magazine, Restless Style, which was started by Jack Abbott, Nicholas Newman, Sharon Newman Abbott and Phyllis Newman. The article was to be approved by Victor and Sabrina and show her in a good light. However, Jack was intent on selling more magazine copies, so he got in contact with sources, including Sabrina's recent ex-boyfriend, and made changes that portrayed her as a woman who would do anything to get ahead — including sexual favors. Sabrina was livid and embarrassed over the article, and especially angry at Victoria because of her accusations. However, she did not let it get to her and she kept her head held up high. In July 2008, she was helping to plan a charity gala that would soon be taking place in Genoa City. On August 1, 2008, she was involved in a fatal car crash along with David Chow and a limo driver, and subsequently miscarried her child. The crash was an intentional attack on David, as a hit had been put out by the mob. Sabrina had asked David to take her home from the charity gala because she was not feeling well. David and the driver were killed instantly but Sabrina was soon found by police alive and was rushed to the hospital. The doctors at the hospital, including experts and specialists brought in at Victor's request by attorney Michael Baldwin, said she did not have much time to live. She needed a liver transplant, as hers was lacerated. However, according to the doctors, there were more needy and longtime transplant candidates ahead of her and she could not be moved up the list quickly enough. Towards the end of her life, Victoria made peace with her and they were friends again. On August 5, she died soon after going into cardiac arrest and could not be resuscitated. After her death, her possessions were given to charity. Her funeral was being planned by Jana Hawkes at Victor's request, but was unexpectedly canceled by Victor so that he could attend Sabrina's burial alone.

Several weeks after Sabrina's death, Nikki Newman had numerous dreams that Sabrina and a little girl, presumably Sabrina and Victor's miscarried child, were talking with her, causing her to feel extremely guilty about Sabrina's death. David Chow also appeared in some of the dreams, telling Nikki that she was at fault for Sabrina's death, despite her having nothing to do with it in reality. Victor also accused Nikki of having a hand in her death because he felt that she had brought David into their lives by marrying him. This caused Nikki to become extremely upset several times, but eventually the dreams and accusations from Victor stopped.

Sabrina appeared as a ghost on September 24, 2008, when an emotional Victor asked her to come and take him, but Sabrina refused to take Victor along. Sabrina reappeared as a ghost on June 1, 2009, when Ashley Abbott Newman dreamed that she was in front of a statue of Sabrina on the Newman Ranch, which Victor had paid someone to create before her death. Ashley asked Sabrina to give her and her baby peace. Sabrina told Ashley not to be afraid, that she was completely sane, and did not need to worry anymore because as long as Victor was happy that is all that matters to her. Sabrina also tells Ashley that she is giving Victor what she had hoped to give him (a baby) before she was "called away."

Sabrina made subsequent appearances to Ashley in her mind (hallucinations) over the course of the next several months in 2009 while Ashley was having mental problems and believed Sabrina to somehow be alive and trying to "take her baby." Ashley's mental distress eventually resulted in her having a miscarriage when she fell down the staircase at the Newman Ranch after thinking she saw Sabrina and trying to run away from her. However, she had actually seen Victor's son, Adam Newman, who was wearing a dress similar to the one Sabrina was wearing the night of the car accident that killed her and playing an audio recording of Sabrina's voice to scare Ashley and cause her further mental anguish. After the miscarriage, Ashley's visions of Sabrina eventually stopped and Ashley's mind tricked her body into thinking it was still pregnant, which a doctor later deemed was a "hysterical pregnancy." Sabrina did not make any further appearances to Ashley after August 2009.

On December 23, 2010, Sabrina appeared to Victor in a dream he had along with Hope Wilson and Colleen Carlton as the "ghost" who was showing Victor the present, while Hope showed him the past and Colleen (whose face was not shown) showed what the future would be like if Victor continued treating his family badly. This dream prompted Victor to go see his family and friends on Christmas, despite the fact he was planning on spending Christmas alone.
