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.

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

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 realise what she had lost.

The insider said: ''She'd already been missing Russell. Being back there stirred up even more old feelings.''

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.''

Russell - who waived his right to a chunk of Katy's wealth in the divorce settlement, which is set to be made official in June - has previously insisted he is already over the split.

He said: ''I'm doing well. You don't need to brush it off if you don't get it on you in the first place.

''I don't have to let anything go. I don't hold on to anything negative. It's the same as zero-ness.

''It's not about letting it go. You can't let go of something you don't hold, you know. It's meaningless, [and] much of our world is predicated on meaninglessness. And I don't do that anymore.''
