Not Ron Burgundy! Christina Applegate was worried about the state of Will Ferrell’s marriage to Viveca Paulin when they were filming 2004’s “Anchorman.” The former co-stars looked back on the misunderstanding on Tuesday’s episode of Applegate’s “MeSsy” podcast. “Christina, do you remember how you thought I was having marriage problems?” Ferrell, 56, asked.

“When we were shooting the movie, we would go out a lot socially,” he recalled to Applegate, 52. “We would all go out as a group, like, on the weekends or whatever, grab a dinner. And, I was like oh great, let’s do it! And then Viveca kept having to cancel.

You verbalized it later. I could tell you were like, ‘What’s going on? His wife’s not coming again.’ “ Ferrell, who married his wife four years before “Anchorman” came out, said that Viveca “wasn’t feeling good” because she was pregnant at the time with their oldest son Magnus.

“We finally could announce that she was pregnant halfway through filming,” he explained, reminding Applegate, “You were like, ‘I knew something was up!’ “ “It’s coming back to me a little bit,” said Applegate. “I remember you guys had something you weren’t sharing yet. A pregnancy.

” The “Dead to Me” actress praised Ferrell and Paulin, 55, and said they’re “couple goals across the world.” She also noted how “incredible” it is that their other “Anchorman” co-stars, Steve Carell and Paul Rudd, are both still mar.
