The mole revealed: "[Russell] got angry with Katy because he thought she had drunk too much. Perry ended up staying with a friend who has a place in N.Y.C. and Brand went back to the couple’s hotel room alone."
Meanwhile, the I Kissed A Girl hit maker is also said to have problems with ex-lothario Russell's womanising ways with the source stating: "There have always been fights about other women − despite Russell talking about how much he loves Katy all the time,"
The insider claims that shortly before last month's MTV Movie Awards, the couple had a huge bust-up after Katy accused Russell of being unfaithful - causing the couple to arrive at the event separately and sit away from each other.
Perry's 'friend' added: "Katy suspected [Russell] of cheating and it wasn’t the first time, it's a cycle."
