Just friends?

Justin Bieber and Kendall Jenner have already posed together for a sexy Vogue photoshoot, and now they're once again creating a stir with their flirty photos, which the 21-year-old "Baby" singer Instagrammed on Thursday.

In the polaroids in question, the two cuddle a dog, with Justin embracing Kendall from behind and keeping his hand on her hip. While the 19-year-old supermodel has insisted the two are just friends before, the affectionate snapshot sure looks like they're dating.

Kendall also posted a polaroid of herself wearing the same bikini on Thursday, though Bieber isn't mentioned in her update.

Though it appears Hailey Baldwin was also present at their hangout. The fellow model, 18, Instagrammed a photo of her and Kendall together, writing, "Good start to Coachella."

In November, Kendall told ABC News that there was no truth to the frequent dating rumors between her and Justin.

"No, he's a longtime friend of our family," she said. "Everybody loves to assume things, but no. I'm truly focusing on my career. If it comes, it comes."
