2013–2016: Vine In 2013, Giraldo was introduced to
Vine, an app for six-second videos, by a friend from drama class. She began posting Vines (videos on Vine) as Princess Lauren aged fifteen, six months after it first launched. She used the name so her mother would not be able to find her online. At first, she created Vines for her friends. Her following spiked after re-vine, a resharing feature, was introduced: after she returned from a cruise before re-vines, her following had increased from three thousand to thirty thousand. Her parents found out about her online presence after she reached one million followers, but were supportive. She had 2.4 million followers in March 2016.
Teen Vogue described her videos as "hilarious" and a "mix of random observations". They typically featured her saying or doing something ridiculous. Due to her young audience, she preferred to keep her videos wholesome. Giraldo did not spend much time planning or creating her Vines, which were often posted after one take. She posted around three times a week and accepted between one and thirty brand deals a month. An article written by her addressed to
Essena O'Neill appeared in
Cosmopolitan in 2015
. After attending her first
VidCon, Giraldo met
YouTubers and was inspired to start a
YouTube channel. Due to her busy schedule, she had to attend
school online. Giraldo moved to
Los Angeles in early 2016 to pursue an entertainment career, aged seventeen. In June 2016, she starred in
Camp Unplug, a series of thirty-six Vines, alongside thirteen other Viners and was nominated Best Actress at the
