Youtube sensation-turned-bestselling author Zoella "Zoe" Sugg turns 26 Monday, March 28, 2016. The brilliant fashion and beauty vlogger, YouTuber and author has gone on to become a role model for young girls worldwide and does her bit to raise awareness about mental health.

Sugg's first book, titled "Girl Online," was published Nov. 25, 2014. The book, which featured a 15-year-old anonymous blogger who finds enormous success in the world of vlogging, has incidences that have the qualities of anecdotes but are not autobiographical. The book became a huge hit and its sequel, "Girl Online: On Tour," hit book stores Oct. 20, 2015.

Sugg, however, is best known for her makeup tutorials and consequently launching her own range of beauty products named Zoella beauty. Thanks to her millions of fans, the launch of her products was immensely successful, leading Metro to call it "biggest beauty launch of the year."

While Sugg soars professionally, she manages to take her army of fans with her, and they know all about her personal as well as professional life. These fans know that Sugg has been dating fellow blogger Alfie Deyes, who is known for his "Pointless Blog" channel.

In celebration of Sugg's birthday, here are some rare and adorable photos of the YouTube couple:
