Three months after her split, a remorseful Katy Perry reaches out to Russell Brand.

India holds special meaning for Katy Perry. It's where her estranged husband, Russell Brand, popped the question in late 2009 and where the couple wed 10 months later in an over-the-top affair. "She regards it as a beautiful and spiritual place," says a Perry family friend. So when the singer made a solo return to the country - to perform at the opening ceremony for the Indian Premier League of pro cricket players April 3 - she couldn't help but feel a bit nostalgic. "She'd already been missing Russell," a close pal admits. "Being back there stirred up even more old feelings."

Not to mention a few regrets. At first furious about Brand's December 30 divorce filing, a source says, a lonely and desperate Perry is now second-guessing herself, wondering if she could have done more to save the pair's 14-month union. "She feels guilty that she wasn't there for him more," says the close pal, adding that the eight-time Grammy nominee, 27, questions whether she should have deprioritized her career and caved to Brand's demands to start a family. And though the eccentric former sex and drug addict, 36, was hardly an ideal husband - he lashed out when she spent time with her friends, say insiders - Perry has been reaching out to him. "Katy's been trying to get him back!" says the close pal, adding, "She's a lost soul right now."

Second Thoughts

Three months ago, Perry was more interested in revenge. The singer channeled her anger into the bitter ditty "Part of Me," and told pals she was thrilled to be single. When her ex stepped out with Hungarian model Nikolett Barabas, 32, Perry retaliated with a model fling of her own: In early March, she hit the Paris nightclub scene with 22-year-old Baptiste Giabiconi. But the romance was quick-lived. "He was a plaything," a pal says of the French-bred fashionisto. "Just to show Russell she was doing OK."

But Perry - whose upcoming concert movie documents her reaction to the split - still pined for her mischievous ex. "She's had moments of sadness," says an insider. And her sentimental India travels continue to resonate. "Now she wants to get back into yoga," says the close pal. "That was something he was always more into than she was."

Russell's Regrets

Perry's not the only one doing a little reflecting. The newly single Brand "was having flings, but he didn't connect with anybody," the pal says of the British comic. "It just felt empty." Still, regrets aside, a reconciliation is a long shot: The couple's divorce will be finalized in July. Says the Perry pal, "Right now, Katy and Russell are trying to get to the point where they can at least be friends."

Russell Gives Up The House

In her breakup anthem "Part of Me," Katy Perry tells her ex to "keep everything." Apparently, Russell Brand didn't get the message. In a recently filed quitclaim deed, the comic - worth an estimated $15 million versus Perry's $55 million - surrendered his rights to the seven-bedroom $6.5 million Hollywood Hills pad they purchased last June. "Katy's happy with the way Russell handled the financial side of their divorce," says a pal of the pair, who had no prenup. "Her money paid for that house!"
