The _Neighbors_ co-stars joined _Tonight Show_ host Jimmy Fallon for his recurring bit “Ew,” where he acts as a teenager and is joined by his best friends to discuss what’s cool and what’s not. Efron, 26, and Rogen, 32, are not the first stars to impersonate tweens for Fallon’s “Ew” segment. Other celebrities who have joined the host in the past include Channing Tatum, Will Ferrell and Lindsay Lohan. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/90800/seth-rogen-zac-efron-teen-girls/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/90800/seth-rogen-zac-efron-teen-girls/"},"headline":"Watch Seth Rogen and Zac Efron As Teen Girls","datePublished":"2014-05-07T14:41:11.000Z","dateModified":"2026-02-21T07:42:01.969Z","description":"The funnymen dressed up in drag last night on The Tonight Show","url":"https://time.com/90800/seth-rogen-zac-efron-teen-girls/","keywords":["celebrities"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/bltf7217ed3f98adc2f/69868e36cd68487255094854/nbcgrab1280x720.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"TIME Video","jobTitle":null,"url":"https://time.com/author/time-video/"}],"articleSection":"Entertainment","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/bltf7217ed3f98adc2f/69868e36cd68487255094854/nbcgrab1280x720.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"Zac Efrov and Seth Rogen on the Tonight Show","caption":"Zac Efrov and Seth Rogen on the Tonight Show","creditText":"NBC","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/entertainment/","name":"Entertainment"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/celebrities/","name":"celebrities"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/90800/seth-rogen-zac-efron-teen-girls/","name":"Watch Seth Rogen and Zac Efron As Teen Girls"}}]}] ```
