Wedding bells are ringing! Gwen Stefani and Blake Shelton's engagement announcement is forthcoming, according to a new Us Weekly.

So that means he's already proposed ... that means they're ALREADY engaged! The two Voice coaches have been dating since 2015 and apparently Stefani's three boys are in love with the country singer. Gwen and Blake have collab'ed together musically; travelled together; worked together -- they've done it all and their relationship has endured so putting a ring on it seems like the next natural step!

Back in April, Gwen gushed to Ellen about her boyfriend and hinting at marriage ...



So when will these two start sending out invites? And before that ... how will they make the big announcement? Probably like all celebs (and the rest of humanity) these days -- our bet is that it'll be on social media!
