Matafeo says she prefers not to think of it as a permanent move but rather a bid to take her comedy on a revolving tour of the world.
"I am leaving my home and becoming a permanent international couch surfer," she says. "While Guy's in the UK he can find his own couch."
Acaster is a big deal in the UK. Since launching himself on the comedy scene in 2009 he has won numerous awards and become a regular on TV and radio.
Matafeo, a former Billy T James comedy award winner, doesn't let a serious question about her life go by without tripping Spy.
When asked for a photo with Acaster, she moaned: "Can't you do this story about just me? It's all about me, we seriously are not in the same town enough to have posed for any photos I like."
Spy thinks London will become a permanent base if Acaster has anything to do with it. Matafeo is definitely ready for the slog of working her way up in the UK comedy scene.
