Enough with the secrets, Justin Bieber and Cody Simpson!

The duo have been stirring a lot of buzz with their upcoming duets album. While 'Home to Mama' seems like a taste at what we can expect from a full-length project, the singers have kept mum about the rest of the music. On top of that, they're teasing another secret that's in the works!

Last night (Feb. 2), Cody tweeted, "heading to NYC this week! a couple cool announcements to come tonight." One of the announcements turned out to be him performing on 'Good Morning America' on Friday (Feb. 6), but the other is much more mysterious.

Cody shared a selfie of himself, Justin, Kendall Jenner and Gigi Hadid, along with the super-cryptic caption "Project ..." Truth be told, we were hoping that Cody was going to pull a Beyonce and drop an album for us, but we are intrigued that Kendall and Gigi are involved in the secret.

Could the four be collaborating on a star-studded song? Will Cody join JB, Kendall and Gigi in the modeling world? The suspense is killing us!

Of course, it's worth noting that Cody later shared a photo of himself on the beach with the caption "This week.. #thesunsetglowsandthegardengrows #newmusic," so we're going to assume that he's got a lot of surprises up his sleeve at the moment.
