Natalie Imbruglia dating Branson

Natalie Imbruglia is reportedly romancing Sir Richard Branson's son.

The 'Torn' singer - who recently split from husband Daniel Johns - was seen canoodling with the Virgin tycoon's son Sam during a bash at London's Kensington Roof Gardens.

The £100,000 ski-themed party was held to celebrate Sam - who at 23 is 10 years Natalie's junior - leaving to go on an Arctic expedition.

An onlooker said: "They are pretty besotted with each other and Natalie is even talking about meeting him in the Arctic."

Since splitting from Silverchair rocker Daniel, Natalie has not been short of male admirers. Last month, she was being wooed by Johnny Borrell.

The Razorlight frontman - who was recently linked to 'Harry Potter' actress Emma Watson and previously dated Kirsten Dunst - fell for the gorgeous Australian singer after meeting her at a recent party. The 'America' rocker managed to get her phone number and was reported to have been constantly calling her.
