I Waited In Line With Hundreds Of Teens To Meet YouTube Superstar Michelle ...

Young people love Phan for her friendly, relatable persona, and she's landed national advertising deals with big brands like Lancome and Diet Dr. Pepper.

And as of this week, she's now a published author. Phan's book, ' Make Up: Your Life Guide to Beauty, Style and Success - Online and Off' was released by Penguin Random House's Harmony Books this week.

Phan was in New York City last night to do a book signing at the Strand's Club Monaco store. Business Insider stopped by to check out the scene.

The signing event was limited to the first 250 people, and a line had already formed when we arrived an hour early.

You had to have a copy of the book to get in, and people - mostly young girls - lined up to make their purchases. One girl briefly held up the line when she used a bag of quarters to pay for her copy of the book.
