Jenn McAllister, whose YouTube vlog is nearing 2 million subscribers, has just announced she has a book due out in September -- the latest in a string of young web stars to seek success in print.
Jenn McAllister aka JennXPenn has already seen plenty of success from her popular videos, having worked with brands including Brandy Melville, Old Navy and Mattel and set to star in the upcoming movie "Bad Night" alongside fellow YouTuber Lauren Elizabeth.
Her "Really Professional Internet Person" is being called "a personal and funny guide to creating successful online content and handling the pressures of internet fame" and will include top ten lists, pictures, screenshots, social media posts and biographical stories from the 18-year-old YouTube celebrity.
The book is due out in paperback and e-book formats in September.
McAllister is hardly the first celebrity to parlay success and a strong teen fan base on YouTube into a book deal. Perhaps the most famous success story is UK beauty vlogger Zoe Sugg aka Zoella, whose debut book, "Girl Online," released in November. Despite controversy surrounding claims the book was ghost-written, it became the fastest-selling work by a first-time author in Britain since records began in 1998.
A month earlier, beauty vlogger Michelle Phan added to her empire with a debut book of her own, "Make Up: Your Life Guide to Beauty, Style, and Success-Online and Off."
And in early 2015, British vlogger Tanya Burr released "Love, Tanya," a collection of beauty, fashion, baking and style tips as well as a look at her life, on and off YouTube.
While many recent deals have been focused on young, female vloggers appealing to their mainly female fan base, men are getting in on the action, too. Alfie Deyes of the YouTube channel PointlessBlog -- and the boyfriend of Zoe Sugg -- released his first title, "The Pointless Book," in 2014, and followed up with a second installment, "The Pointless Book 2," this month.
Vlogger Shane Dawson's "I Hate Myselfie," consisting of 18 personal essays about growing up, reportedly sold 100,000 copies in the dozen days or so after it went on sale on March 10.
And coming up just around the time Jenn McAllister will release her debut title, Zoe Sugg's brother, Joe Sugg, a YouTube personality in his own right (ThatcherJoe), will go in a different direction for his debut title: he has a graphic novel planned for release in September.
