Olivia Spencer and Natalia Rivera Aitoro

Olivia Spencer and Natalia Rivera Aitoro, often referred to by the portmanteau Otalia, are a fictional couple from the American CBS daytime drama Guiding Light. Olivia is portrayed by Crystal Chappell, and Natalia is portrayed by Jessica Leccia.

The storyline begins when Olivia and Natalia's relationship starts to evolve following Olivia's heart transplant in April 2008. The couple's relationship subsequently changes from being enemies, to close friends who rely on each other, to women becoming more than friends.

Writing for the pairing was slow to establish the relationship as romantic. Despite this, the couple generated significant interest, not only amongst Guiding Light viewers but also amongst soap opera critics, LGBT-oriented websites such as AfterEllen.com and The Advocate, and mainstream media such as Entertainment Weekly. The pairing became one of the most praised same-sex couples in American daytime drama. Nelson Branco of TV Guide Canada named them 2009's "Sexiest Couple Alive," called the pairing a "fledgling super-couple," and wrote, "In an age of contrived and soulless couples, Olivia and Natalia’s burgeoning romance felt natural, innocent, and most importantly, real."

On April 1, 2009 (despite that date's usual connotations), CBS announced that the 72 year-old production of Guiding Light would cease broadcast on the network after September 18, 2009, effectively ending any long-term plans for the pairing.
