'Crazy Stacked Cast' (Exclusive): That 90s Show Star Callie Haverda Teases Which Guest 'Intimidated' Her in Season 2

The new season of That 90s Show has lots of star power in its guest star lineup — and leading lady Callie Haverdais admittedly intimated by one, in particular.

"It's a crazy stacked cast," Haverda, 17, told PEOPLE at the show's part 2 premiere at Button Mash in Los Angeles on Tuesday, June 25. "I was mainly intimidated by Lisa Loeb."

Recalling how she was "trying to recreate" Loeb's "iconic" music video for "Stay (I Missed You)" for the show, Haverda continued: "I mean, it was definitely intimidating doing that because I was practically being her."

"I've never done anything like that," she explained. "I rewatched her music video so many times."

In addition to Loeb, other all-star guest stars for season 2 include Will Forte,Seth Green, Carmen Electra,Wayne Knight,Kevin Smith,Jason Mewes,Matt RifeandKadeem Hardison.

"All of them are so incredible, and I was intimidated by all of them," Haverda said. "But we weekly became very comfortable with each of them. Seth Green is actually the coolest person in the world. Being able to spend so much time with him, we became very close."

Continuing to rave about Green, she added, "He is so iconic and he doesn't present that way. He doesn't come to set, and he's not flaunting that in any sort of way. He's just very easy to get along with."

The series returns to follow the fun and mischievous teen rebellion ahead for Eric Forman (Topher Grace) and Donna Pinciotti's (Laura Prepon) daughter, Leia Forman (Callie Haverda). Leia reunites with her boyfriend, Jay (Mace Coronel), and their friends Gwen (Ashley Aufderheide), Nate (Maxwell Acee Donovan), Ozzi (Reyn Doi) and Nikki (Sam Morelos) for a jam-packed summer.All the while, Leia will be staying under her grandparents Red (Kurtwood Smith) and Kitty Forman's (Debra Jo Rupp) roof.

Per a synopsis from Netflix about the new season, "It' -

"Nate is concerned that his girlfriend, Nikki, doesn’t know either. How long can they keep this secret? Turns out, not long at all," the description continues. "And when the truth finally comes out, relationships are threatened, friendships are at stake, and the summer is on the verge of ending before it even gets started."

Although Prepon, Smith, Rupp and Don Stark will reprise their roles, they are the only former That 70s Show actors returning for the second season. Even though Wilmer Valderrama, Mila Kunis,Ashton KutcherandTopher Grace all reprised their roles for the first season each have confirmed they will not appear in the upcoming season.
