Phill Lewis chats and poses with the stars of Good Luck Charlie during a break from filming.

In “Bye Bye Diary,” When all of Teddy’s (Bridgit Mendler) video diaries get lost after her laptop gets ruined, she and Amy (Leigh-Allyn Baker) stay up all night recreating the first 50 diaries for Charlie (Mia Talerico).

Meanwhile, while PJ (Jason Dolley) enrolls in Kwikki Chikki University management training and spends the weekend having a “college experience,” Gabe (Bradley Steven Perry) takes advantage of the room and watches a scary movie, but he gets so frightened that he makes Charlie sleep in the room with him.

“Bye Bye Diary,” directed by Phill, premieres THIS SUNDAY, June 19 @ 8PM ET/PT on Disney Channel. 10+ pics inside…
