In 2000, when Shaina was 10 years old, she released a self-titled debut album with Star Records. The carrier single was “Sayaw Sweet Lullabye”. The song’s music video was often played in the afternoons right before Marinella or youth-oriented shows.
Shaina has also played daughter to a very wide-range of celebrity “parents” on the big and small screens. It was a role like this, in 2000 for the Laurice Guillien helmed project Tanging Yaman, that won her a Best Child Actress award from the FAMAS (Filipino Academy of Movie Arts and Sciences Awards), and Most Popular Child Actress Award from the 2001 Guillermo Mendoza Awards. She has also spoofed this award-winning role in the Ai Ai De Las Alas starrer, Ang Tanging Ina. She had also previously received the Best Child Performer award from the Parangal ng Bayan in 1999, and Best New TV Personality in the 1996 Star Awards.
Since then, Shaina has slowly but surely been building her career over the years. In 2002, she starred in a light weekend afternoon series, called K2BU, where she met half-Brit Bea Alonzo, who is her best friend. She has appeared in several drama series and sitcoms, and at one point, doing three at the same time (Seasons of Love, Bida si Mister Bida si Misis, Kay Tagal Kang Hinintay), while going to regular school. She started to be home-schooled in late 2004, as her schedule got even more hectic, but will be graduating at the same time as Pop Princess Sarah Geronimo.
In 2005, she was included in the cast of the much underrated primetime drama series Ikaw Ang Lahat Sa Akin, along with Claudine Barretto, Diether Ocampo, her best friend Bea Alonzo and John Lloyd Cruz. It was here that she was paired with actor-dancer Rayver Cruz, who she is currently still being paired with.
She is currently still taping for the Chito Rono and Erik Matti’s newest television series, Rounin, set to air in January or February 2007. She is currently starring in the afternoon light drama Star Magic Presents: All About Your Love along with her loveteam, Rayver Cruz and 17 other young stars under Star Magic. She is also a semi-regular at ABS-CBN’s Sunday noontime variety show, ASAP 06. Magdayao is a member of ABS-CBN’s elite circle of homegrown talents properly named Star Magic.
