Moving vans have been spotted at Katy Perry and Russell Brand's house.

Two trucks were parked outside the former couple's Hollywood Hills home - which they bought for $6.5 million in June - on Wednesday but it is not clear whose belongings were being shipped out of the property, TMZ.com reports.

Since filing for divorce on Dec. 30, Russell has been staying in his native U.K. while it has emerged the 'E.T.' hitmaker has sought solace with her grandmother.

A source told the Daily Star newspaper: "Katy drove down to Santa Barbara to spend time with her favourite person. They're extremely close. Katy always runs to her granny when she's in trouble.

"She's been making Katy her favourite pineapple and beetroot salad and giving her a real dose of family love and strong advice about how to heal a broken heart."

Meanwhile, Katy's parents, Keith and Mary Hudson, joked their daughter's troubles had brought more people to hear them preach.

The evangelical Christian ministers addressed the congregation at the Church on the Rise in Westlake, located outside Cleveland, Ohio, and admitted people find them more approachable because of the pop star.

Mary said: "I'm sure that Katy's trending on the Internet was to get you here to church tonight."

Keith added later in the service: "You don't need a verse or a scripture. You don't need Katy Perry's father. In the news they call us, 'Katy Perry's parents are religious.' Do I look religious?"

"What has taken place in my daughter's life has opened many opportunities to go in and be with guarded and gated people. They like us because we're cool. We are not threatening."
