Zac Efron joined "Neighbors" costar Seth Rogen and host Jimmy Fallon as the trio stripped off their masculine clothing to dress in drag on Tuesday as part of "The Tonight Show's" recurring sketch, "Ew!"

Fallon who plays TeenNick host Stacy Wallace decided to kick off her fictional television show by inviting her "bestie" Allison Donnelly (Rogen) to join her on the couch for some girl talk.

According to E! News, the two "girls" chatted about typical teenage routines. Allison explained, "My mom gave me her credit card so I stopped by Starbucks on the way here."

To which Stacy replied, "Ew!" Quickly adding, "What did you get?"

"A venti soy cinnamon dolce cream Frappuccino!" Allison responded.

When asked if she got whipped cream as well she said, "Ew! Of course!"

Just as we are about to learn more about Allison's iced drink Brittany Anderson (Efron), the girls' other best friend shows up. The "teen" arrives, alerting her friends that she has big news.

She revealed, "I'm actually super excited right now because I just got this new phone and it has an amazing camera," adding, "It's got, I think, like, eight megapixels-so it's like perfect for selfies! I've been taking them all day!"

After a series of selfies the girls begin to talk about music. Brittany tells the group, "There's this one song that I just cannot get out of my head," adding, "It's called 'Turned Down for What.'"

The girls soon launch into a twerk session until they received an annoying interruption.

"Ew! It's my stepdad, Gary!" Stacy says. Adding, "He's so lame!"

After an awkward moment the girls talk about Crocs, tomatoes, baby sloths, Gary Oldman and James Franco.
