Justin Bieber and Kourtney Kardashian got into the Halloween spirit and hit up Hollywood Horror Nights in LA on Friday. The 21-year-old singer took to Instagram on Saturday to share a captionless snap of the pair wearing 3D glasses and serving up some serious face. Now this isn't the first time we've seen these two together, as Justin is a friend of the Kardashian-Jenner family and often hangs out with Kendall and Kylie Jenner. Back in March, Justin shared a sweet moment with Kourtney's son Mason [2], splashing around in a pool.

Justin's outing comes just a day after his legal team threatened to sue [3] over the nude pictures that were posted earlier this week, adding him to the list of celebrity guys who have dealt with nudity scandals [4]. Meanwhile, Kourtney has continued her flurry of flawless appearances [5], and she covers the November issue of Cosmopolitan [6] alongside her famous mom and sisters.
