Katy Perry and Russell Brand break up 'shocked' friends
"I was shocked when I found out," the source tells People. "I was really surprised that Russell filed for divorce so quickly - especially at Christmas time...I thought they would be together for a long time. Maybe not forever - but definitely not just 14 months."
The source adds, "They were always laughing. They were very affectionate, always holding hands. They seemed like they were really in love."
A second source echoes the sentiment that the Hollywood couple seemed focused keeping the relationship together.
"These aren't people who give up," the second source says. "I always thought they would work on their marriage if they had trouble."
Brand, 36, filed for divorce from Perry, 27, on Dec. 30.
