|—Rebecca's former catchphrase|
Rebecca Guglielmino is a supporting character in the first two seasons of Alex & Co. and a main character starting in Episode 42 of Season 3. She was Linda and Samantha's best friend and the second most popular girl at the Melsher Institute. She used to reply to everything Linda said with "absolutely," and used to follow Linda around everywhere.
In the second season, Rebecca began to get tutored by Sam and found out that she could sing. She and Sam fell in love, and he wrote a song for her called "Likewise". They later started a relationship, which they kept a secret because of their friends, and Sam helped Rebecca break away from Linda. Rebecca discovered she had within her a lot more than she thought, and thanks to Sam has found the courage to bring out her personality and her musical talent.
In the first part of Season 3, after arguing with Linda, she started to make new, true friendships, and supported Sam in all of his endeavors. In the second part, she suffered while trying to cope with Sam's moving abroad, but she met a new guy, Matt.
Rebecca is portrayed by Giulia Guerrini.
In the first season, Rebecca is shown to just be a pretty face. She is shallow, naïve and most definitely can't think for herself. She wears the same colors as Linda in most episodes, but sometimes only wears a small fraction of that color. However, in Season 2, she starts to spend less time with Linda as she starts being tutored by Sam. With him, Rebecca shows a much more kinder and eager to learn side, which is most likely fueled by her falling for him.
Rebecca has blonde hair. She often wears it down. She wears a lot of pink and black. She often wears a long sleeved shirt, a skirt and tights or pants.
She has been Linda's best friend since before the series started, when they were at the kindergarten.
