The 31-year-old singer, who announced her split from Chad Kroeger last month after two years of marriage, fuelled speculation she's already moved on with the 33-year-old musician after they were spotted shopping for pumpkins in Beverly Hills earlier this week.

But a source told UsMagazine.com the duo are "just friends."

The 'Hello Kitty' hitmaker previously insisted she and Chad, who fell in love when they collaborated on her last album, are still on good terms and plan to continue working together in the recording studio.

She posted a photograph of the Nickelback frontman, 40, on Instagram, with the caption: "YeeHaw! Writing with Chad today. Back where it all started..."

A source previously claimed the pair decided to split because "they didn't see eye-to-eye on a lot of things."

The insider added: "They originally got together to make an album and that's where the spark between them originated. But it just slowly died out.

"They talked about having kids but it just never happened.

"At the end of the day, they just didn't see eye to eye on a lot of things."
