Florence Welch "instantly hit it off" with her new boyfriend.
The Florence and the Machine singer is currently dating event organiser James Nesbitt.
The pair are reportedly smitten with one another.
"Florence and James are pretty loved up," a source told British newspaper The Sun.
"They instantly hit it off. James was privately educated in Yorkshire and now earns his cash from helping organise events."
Florence is currently on holiday with James in Rio de Janeiro, Brazil. Before visiting South America together, the couple vacationed in Australia and New Zealand.
Friends close to Florence believe that she has fallen hard for James.
"They have a lot of mutual friends and like going out to the same places," the source revealed.
"They have been inseparable since they got together. There's no way they'd travel half way around the world together if they weren't serious."
James was previously romantically linked to UK television presenter Fearne Cotton.
Florence split with her long-term boyfriend literary editor Stuart Hammond in October 2011.
The songstress has been nominated for Best Female and Best Album for Ceremonials at next month's BRIT Awards and she is currently preparing for a world tour.
