Katy Perry and Russell Brand have been rumored to be having some issues in their marriage lately, so much so, that they have had to fend off divorce rumors during the past few months.

However, according to Us Weekly it looks like things actually are starting to go downhill for this originally perfect couple! The mag reports that the duo, who have been married for more than a year, spent Christmas apart after having a massive fight! A source explained just one of the reasons for the fighting this holiday season: "Katy doesn't think Russell respects her parents' Christian beliefs or her friends."

Although Perry originally planned to spend the holiday in Brand's London hometown, she changed her plans at the last minute and was spotted in Kauai on Christmas Day, while Brand was seen with a pal at a pub in Cornwall. "They havent split up just yet, but things are not good," a second source explained. "The fighting is getting worse."

Hopefully these two former lovebirds can work out their differences and bring a more positive vibe to their relationship as we get into the New Year!
