Things seem to be going very well for the couple, who first went public with their romance back in August, and Mario announced their exciting moving news on Instagram on 2 October.
He shared a photo of himself with Becky in the car, adding the caption: "Today I am a happy man.. My girlfriend has moved into mine and made it our home."
Mario added two emojis, one of a couple and one of a house, along with the hashtag, "#blessed."
News that they are now living together comes after Mario hinted his relationship with make-up artist Becky is the real deal. The reality star is often posting pictures of himself and his girlfriend to social media, and has been seen referring to Becky as "the wife."
Becky has even met all of Mario's family, including his nephews Buzz Fletcher and Buddy Fletcher (his sister Giovanna's children with husband and McFly star Tom Fletcher). Mario is often seen gushing over the babies in his family and speaking to Reveal last year, he told us he would love to have a family of his own.
Mario said: "I would love to have that, but I don't want to rush into something with the wrong person. It will happen when it happens."
Perhaps Becky could be the right girl for him?
Mario was previously linked to ex-girlfriend Emma McVey. They dated for nearly a year on/off, before splitting for good in October last year.
Back in February, this year, Mario found himself at the centre of rumours he and his ex-fiancée Lucy Mecklenburgh could rekindle their romance - following her split from Louis Smith. Lucy dismissed the claims and ruled out a reunion, while Mario insisted "some things just aren't meant to be."
He told Daily Mail: "We get along well. We say hello, have a drink, but that's all it is. I think that's all it will ever be... with me and Lucy some things just aren't meant to be and it wasn't meant to be."
