Diaz And Timberlake Party On Plane

Superstar couple Cameron Diaz and Justin Timberlake thrilled passengers onboard the first class section of a jet - by throwing a pyjama party.

The pair popped open a bottle of champagne on the QANTAS flight from Los Angeles to Melbourne, Australia after stripping their clothes off in favour of the airline's sleep-suit - and began mingling with their fellow travellers.

Following reports last weekend June 5th & 6th that Diaz had split with Timberlake to focus on her movie career, the sexy pair proved they're still very much an item by excitedly chatting to passengers and playing games with them.

One passenger says, "They were in very high spirits and are very clearly still in love. They were chatting to loads of passengers. As soon as they got into the air they changed into their free first-class pyjamas and ordered a bottle of champagne.

"People were going up to speak to them and they seemed really happy.

"Cameron produced a travel version (of ancient Chinese game Mah Jong) and invited other first class passengers to join in. Then they watched their friend Drew Barrymore's film 50 First Dates before settling down for a nap."

Timberlake - who flew out to Australia with Diaz on Tuesday - is spending 10 days in the country performing at concerts.
