Emma Roberts is about to surpass Miley Cyrus, Dakota Fanning and half-a-dozen others on the Young Hollywood A-List of hotties. After all, she is Hollywood royalty and her latest films are light years ahead of her peers.

Roberts, 19, has already logged a dozen movie credits and with an aunt like Julia Roberts — her father is actor Eric Roberts — she’s already established her Hollywood cred. Yet, she appears to be remarkably down to earth.

She was scheduled to appear on “Late Night with Jimmy Fallon” in New York City, Thursday night (Oct 7) and she gushed like a little kid, although she’s no kid, judging by her latest film roles.

“Heading to @jimmyfallon show! Super excited. Had fun the last time I was on! Everyone make sure you watch!” she tweeted.

Later she added: “Jane Lynch is the other guest on Jimmy Fallon with me…I think I just peed my pants!!!!!!

Like most of Young Hollywood, Emma is trying to make the leap to adult film roles, and she goes along way toward that goal in her next film

Emma stars in “4 Girls, 3 Days, 2 Cities, 1 Chance” (aka 4.3.2.1). She she strips down to to bra and panties in a sexy scene.

She’ll also appear in the Nov. 2010 issue of Marie Claire magazine.
