"And your co-star Jamie Lee Curtis is presenting tonight, have you seen her?" ET's Leanne Aguilera asked Chlumsky.
"Just ran into her! I haven't seen her in so long, and yeah I'm so happy," the 34-year-old Veep actress, who was wearing a cream Bibhu Mohapatra gown, said. "I was so happy to see her. But of course there's like a frenzy here so we're going to get together elsewhere sometime… on another day."
Well, looks like another reunion took place sooner than she expected. As ET was chatting with Chlumsky about the new season of Veep, Curtis was walking by, and quickly jumped in on our interview.
"She's amazing. She's taught me everything I know," Chlumsky said, giving the 56-year-old Scream Queens star a kiss on the cheek
In the 1991 comedy drama, Chlumsky played tomboy Vada Margaret Sultenfuss, an 11-year-old girl who faced many emotional challenges -- her mother died giving birth to her, her father operated a funeral service out of their home, her best friend was a boy (Macaulay Culkin) and she had a crush on one of her teachers, to name a few. Curtis played Shelly DeVoto, a make-up artist at the funeral home, who Vada confided in.
Chlumsky is a nominee at this year's Emmys for Outstanding Supporting Actress in a Comedy Series for her role on the HBO show. Veep received six nominations including Outstanding Comedy Series, Outstanding Directing for a Comedy Series and Outstanding Writing for a Comedy Series.
