Stars like Kristen Bell and Andy Samberg are set to hit the orange carpet on Saturday for the 2014 Nickelodeon Kids' Choice Awards.
This year's slime-tastic event will be held at USC's Galen Center in Los Angeles.
In addition to Bell and Samberg, other big names expected to attend include "Captain America" star Chris Evans, pro wrestler John Cena, "Live!" talk show host Michael Strahan, Tia Mowry-Hardrict, Lea Michele and Will Arnett, among others.
Pop singer Austin Mahone will be performing live on the orange carpet in the lead-up to the show, while rock group American Authors and rapper Aloe Blacc are expected to perform during the event.
"We can't wait for him to host and have lots of slime-filled fun with Hollywood's biggest stars and our audience," Russell Hicks, Nickelodeon's president of content development and production, said in January when Wahlberg was first announced as host.
Viewers have until the day of the awards show to cast their votes for the nominees.
The 27th annual Kids' Choice Awards will air live on Saturday at 8 p.m. ET on Nickelodeon.
The carpet pre-show begins airing at 7:30 p.m. ET.
