Endearing and witty, undeniably funny and one of the hardest working people in show business, Ross Mathews has won the hearts of millions of Americans since his television debut as a correspondent for The Tonight Show with Jay Leno.

In May, Mathews will release his first book, Man Up: Tales of My Self Delusional Self-Confidence. With an introduction written by Gwyneth Paltrow, and afterword from Chelsea Handler, Man Up takes readers inside Mathews’ personal journey as a super fan, revealing the most embarrassing and hilarious moments of his small town life and big city adventures, and how he managed to turn an obsession with pop culture into one-on-one interactions with celebrities—without ever having a single restraining order issued against him.

In addition to Man Up, Mathews is a regular panelist and occasional guest host on E!’s late-night talk show Chelsea Lately, and is a fixture on E! News and E! Network’s live red carpet awards show coverage.
