Britney Spears is in the ''beginning stages'' of planning her wedding.

The singer and 'X Factor USA' has been engaged to her manager, Jason Trawick, since December 2011, but admitted they haven't gotten far with the wedding yet.

When asked how the nuptials are going, she told US TV show Entertainment Tonight: ''Pretty good. We're getting there.''

She continued she and Jason are in the ''beginning stages'' of organising their union.

The 30-year-old also admitted to being a stickler for organisation and cleanliness at home, while Jason, 41, is the polar opposite.

Britney said: ''I'm OCD. I'm like, to the point where I'm completely anal and he's the complete opposite so we really butt heads in that department.''

When asked about the most organised room in their house, she said: ''All the rooms. Even the refrigerator is completely organised. Everything is in its place.''

Britney - who has two has two sons, Sean Preston, seven, and Jayden James, six from her previous marriage to Kevin Federline - has recently bought a new $8.5 million house in the quiet district of Thousand Oaks, 40 miles outside downtown Los Angeles with Jason.
