Given Kendall Jenner’s famous family, it’s no surprise that she’s also amassed slew of celebrity friends. But Selena Gomez? We totally didn’t see that one coming!

The 18-year-old model and 21-year-old singer were photographed leaving lunch in L.A. on Friday, March 21. The duo were spotted slipping out of trendy eatery Joan’s on Third, before sharing a hug and going their separate ways.

As is typical of her model-off-duty style, Kendall looked chic yet casual in an oversized denim shirt and super skinny jeans. She paired the ensemble with a classic Hermes clutch and sky-high white heels.

Selena Gomez looked equally adorable (yet a bit more bold) in a paisley-print crop top and matching slouchy pants. She, too, color-coordinated her accessories, carrying a large Hermes handbag and wearing white, strappy heels.

Though we were initially surprised to see these two hanging out together, it does make a lot of sense. After all, they both have a penchant for bad boy singers. (Kendall briefly dated One Direction’s Harry Styles, while Selena has continued to have an on-and-off relationship with Justin Bieber.)

Perhaps Kendall was imparting some words of wisdom to Ms. Gomez? (We only hope those words would be “It’s time to dump that kid already.”) Then again, Kendall was probably just showing her support. After all, the Jenner girls have been friends with Justin Bieber for quite awhile, with Kendall’s little sister Kylie calling him “such a good guy.”

What do you think of Kendall and Selena’s friendship?
