"There's all sorts of things coming up but things I probably can't talk about right now. But I've got a very busy few years ahead of me."
The Canadian singer - who has son Eja, 21, with ex-husband Robert 'Mutt' Lange and is married to Frederic Thiebaud - spent a long time in London working on her new album but has ruled out a permanent move to the UK because she wouldn't be able to secure her dream home.
She explained: "If I could live at the stables in Hyde Park, I would. I just want to live next to the horses each morning.
"That's been my dream for many, many years and I've asked a lot of people but I don't think it's going to happen."
It comes after the pop star dived deep into her past for her Netflix documentary.
The documentary titled Not Just a Girl which was released in July chronicles Twain's journey from small-town Canadian performer to global superstar and goes into depth about the star's relationship with music producer Lange whom she married in 1993.
