Selena Gomez had to explain "OG" and "WAP" to Steve Martin while filming Hulu's Only Murders in the Building

“There was a line in the script that said, ‘She’s an OG.’ And Steve walked up and said, ‘Can somebody tell me what OG means?'" Gomez tells Elle magazine. “I started dying laughing.” On another occasion, she taught Martin the lyrics to Cardi B and Megan Thee Stallion’s sex-positive summer anthem “WAP." Gomez tells Elle she loved working with the older actors. “I got to be in a space with so much wisdom,” she says. “They became my uncles.” Martin echoeds the sentiment: “We ended up feeling very close to Selena.”
