AWKWARD! Justin Bieber and wife Hailey Baldwin were trying to have a romantic dinner date Friday night at celeb hotspot Matsuhisa when who walks in but Justin's former hookup Chantel Jeffries!

The YouTuber/singer/model arrived with a gaggle of gals in her white Porsche Macan, went in for some sushi and left 15 minutes later!!! Did she and her pals really fill up on sake and spicy tuna roll that quickly? Doubt it ... she likely got side-eye from Hailey and bolted!
