Is A New Justin Bieber Track Dropping Next Week?

After Lil Dicky tweeted out that he's dropping a new song and video next week, rumors were triggered that it's a collab with Justin Bieber after Biebs retweeted it.

I mean, what if he's just supporting his friend and spreading the word...assuming it's a collab based off a retweet is jumping to conclusions a bit, isn't it? (It's probably def a collab though.)
