Longtime couple Justin Timberlake and Cameron Diaz are still going strong, according to a source who vehemently denies a published report that they have split up.

"The couple are in fact very much together, as he prepares for the release of his album," says the source, who is close to Timberlake. "Of course, made-up sources have had them breaking up, getting married and having a baby ever since they began dating over three years ago."

Earlier this week, a report claimed that Timberlake – who is slated to release his new album, FutureSex/LoveSounds, on Sept. 12 – had broken up with Diaz. The story cited their age difference – he's 25, she's 33 – one of the reasons why.
