The collaboration may not come as a total surprise - the controversial pop star opted for Jacob's creations at a bunch of different appearances last year including the Met Ball.
Cyrus has sung her praise for the designer, telling Hunger TV in October that she has worked a lot with Marc Jacobs.
"He kind of brought me into fashion when I was 16, that was when I started being around him and just learning from him. He let me inspire some of his pieces and now I feel like it's just about having the right people around you," she said.

The shoot is bound to stir some controversy - but no more than Cyrus is used to.
Stars from David Jason to Kate Winslet have waded in on the great debate about Miley and her hyper-sexualised pop star antics of late.
Earlier this week, the Touch of Frost star described her as an example of the eroding standards of modern society.
"She has done it to break the mould," he told The Sun on Sunday. "I can understand why, but we have given her the oxygen of publicity and encouraged it, so young girls will think it is the right way to attract men. We've lost our standards.
"Once upon a time if you said this or did that, you'd be off the air. They wouldn't dare show it.
"It slowly drip feeds, erodes standards of politeness, manners and morality," he continued.
"It just drips and it takes us further and further down, and instead of inspiring us to look up, we are all going down."
"You hear horror stories where you think, 'God, who's looking after these people and why does it seem like they're losing their way?'" Winslet similarly told Psychologies magazine.
"I mean, you think about someone like Miley Cyrus, and I said to my daughter the other day, 'I'm this close to opening my mouth about what's going on with that girl'. Who is actually saying, 'Stop for a second, what do you want, who are you?'"
Their comments come after Cyrus released her latest talking point: the music video for Adore You. In it, the singer is seen writhing around scantily-clad under bedsheets while she simulates masturbation.
But she's not all sex and no substance: the star showed her support for the LGBT community by posting a photo of herself wearing a pro-gay rights campaign T-shirt designed by Marc Jacobs on Twitter two days ago.
