Showing some skin! Hailey Baldwin's got it, and she's gonna flaunt it! The sexy supermodel wore a revealing red silk dress to dinner Tuesday night with Justin Bieber and the slit at the thigh was WAY more than thigh-high -- that cut went up to her waist!

Her assets on full display, Justin appeared to be a happy man as the pair made their way into Nobu Malibu for some sushi. Justin wore a Fear of God jersey-style tee with ripped black jeans while Hailey topped off her sexy halter dress with a leather biker jacket and paired it with on-trend white sneakers.

After having recently adding some new piercings to their body adornments, the couple is fresh off a weekend of worship at the Zoe Church's annual convention. Bieber spent time with friend/pastor/mentor Hillsong pastor Carl Lentz and his mom Pattie Mallette was in town for the event as well.

Justin and Hailey have been together a lot recently, having vacationed at their Ontario, Canada home a couple weeks ago and now, back in LA, they've been inseparable. Inevitably, they'll both have to go back to work at some point, but for now, they're cool for the summer!
