Katy Perry and Russell Brand's secret love pact

They’ve mapped out a plan to ensure they don’t turn into a nagging couple

Katy Perry and Russell Brand have been dogged by rumours that their marriage is on the rocks, but the couple are making every effort to keep their long-distance relationship fresh.

The couple have hammered out a five-point love deal - and friends tell Now it's working a treat as the pair are more smitten than ever.

Katy, 26, starts the US leg of her California Dreams tour this week in Florida, where Russell, 36, is filming Rock Of Ages. And the couple are making the most of their time together.

‘The first new rule is to have date nights each week whenever they're in the US,' says an insider.

‘So when Katy got back to their LA home last month, Russ took her to the cinema to see The Hangover Part II. They sat in the back row and kissed like teenagers - it was like one long foreplay session!'
