Russell Brand 'Mocked Katy Perry's Religious Parents'

Russell Brand is used to making a joke of people during his stand-up comedy routines but the star made a bad move during his marriage after taunting Katy Perry's parents over their religious beliefs.

California Girl singer Katy and funnyman Russell revealed the breakdown of their 14 month union after Russell filed for divorce in Los Angeles last Friday citing "irreconcilable differences".

The couple set the rumour mill into motion after spending Christmas apart but it seems Katy's parents may have banished the Forgetting Sarah Marshall actor from Christmas Dinner.

Speaking to The Sun, a source said: "Russ was forever making lewd jokes at the dinner table and poking fun at her parents' beliefs.

"He managed to restrain himself in the beginning - just.

"But as the marriage progressed, he got worse and kept winding up her family. After the lust wore off, reality hit home about their differences and (Katy) was left thinking, 'What have I done?'"

Teenage Dream singer Katy is thought to have asked Russell to file for divorce to avoid going against her evangelical Christian parents' beliefs as they do not believe in divorce.

Russell, what were you thinking?!
