When "Ramona and Beezus" opens Friday, moviegoers might be wondering how much Selena Gomez and Joey King are like their onscreen personalities. And, as it turns out, there's a bit of Ramona and Beezus in both of them.

"I'm not really comfortable in my skin as much as Beezus is, but I do try to do my best in school," Gomez told MTV News about her character in the film, which also stars "Sex and the City" alumni Bridget Moynahan and John Corbett.

"I have a huge imagination, like Ramona, [and] a big personality, but there's some similarities and some differences between me and Ramona as well," 10-year-old King added.

Gomez has said that King became like a real-life sister to her during filming. "Even when they stopped, when they would say 'cut,' we would still just be as loud and talking. We all got along really well," Gomez said about how "inseparable" she's become with King. "Pretty much, we talk all the time. She's like my sister, and I never had a sibling, so she's as close as I've got."

So does that make Gomez the real-life Beezus to King's Ramona, based on the characters from the beloved Beverly Cleary books? "She's still the Ramona," Gomez said. "I go to her for advice, if anything."

"We both have different traits from each character," King said. "She's like Ramona in some ways and same for me."
