Katy Perry wants to give her relationship with Russell Brand another go. The former couple ended their 14-month marriage in December when Russell filed for divorce citing "irreconcilable differences" - but Katy, 27, has reportedly had a change of heart.

"Katy's been trying to get him back! She's a lost soul right now," a source said.

Russell, 36, has since moved on with model Nikolett Barabas, while Katy has been linked to Chanel star Baptiste Giabiconi. But according to US Weekly, a recent trip to India - where she tied the knot with the Arthur actor in October 2010 - made her realize what she had lost.

"She'd already been missing Russell. Being back there stirred up even more old feelings," the insider added.

However, a reunion may be a long way off with the pair still "trying to get to the point where they can at least be friends."
