Karlie Kloss is wishing Drake a happy belated birthday with a sassy snap.

The 24-year-old supermodel Instagrammed a cute picture of her and her good pal, Taylor Swift, at the rapper's star-studded party at Delilah restaurant on Sunday night, in which the two adorably mug for the camera. Swift showed off her toned back in a crop tube top, as Kloss coyly looked over her shoulder.

"Happy belated @champagnepapi," Kloss captioned the snap.

The cute pic also appeared to reassure fans that Swift and Kloss' super close friendship is still intact. On Wednesday, Kloss hung out with Kendall Jenner at the Los Angeles Lakers vs. the Houston Rockets game at the Staples Center, raising some eyebrows given Swift's feud with Jenner's sister, Kim Kardashian West. Jenner and Swift also both dated Harry Styles at one point.

"Kaylor lives!" one Instagram comment reads.

In August, Kloss took to Twitter to clarify comments she made about Kim, after a few Swifties attacked her on social media. "I think she's been a lovely person to me in the past," Kloss told the U.K.'s The Times about the 36-year-old reality superstar.

"I will not allow the media to misconstrue my words. Taylor has always had my back and I will always have hers," she later tweeted. "And I will never be the girl that you can use to pit women against each other. That isn't me."

Drake's soiree had plenty of potential to get awkward given the guest list. Swift's nemesis, Katy Perry, was also in attendance, as well as John Mayer, who both Perry and Swift dated.
