Earlier this year the Canadian pop star was without fame, but very much in love with her then-boyfriend Jordi Asworth.

She was still head-over-heels for Ashworth (who inspired her to write Call Me Maybe) back in May when she gushed:

"He's an amazing guy. Jordi is studying to become an architect, but right now he's taking some time out to come along and be involved in this adventure with me. It's nice that I don't get lonely."

But time and fame can change everything!

Pals have confirmed that C-Rae has dumped the future architect for fellow musician Matthew Koma. They claim:

"Carly broke up with Jordi in June because her schedule got crazy."
