Justin Timberlake and Beyonce Knowles have scored a leading seven nominations each for this year's MTV Video Music Awards.


Kanye West and Rihanna scored five nominations each, while newcomer Amy Winehouse received three.


MTV also announced that the VMAs will be a one-night stand this year, airing live from the Palms Casino Resort in Las Vegas at 9 p.m. on Sept. 9.

After almost four years together, Cameron Diaz and Justin Timberlake have broken up, the couple said in a statement Thursday.


Cameron Diaz and Justin Timberlake said:

It has always been our preference not to comment on the status of our relationship, but, out of respect for the time we've spent together, we feel compelled to do so now, in light of recent speculation and the number of inaccurate stories that are being reported by the media,

We have, in fact, ended our romantic relationship, and have done so mutually and as friends, with continued love and respect for one another

.


Cameron Diaz, 34, and Justin Timberlake, 25, met in April 2003 at the Nickelodeon Kids' Choice Awards, and by July, Diaz had joined her new boyfriend on the road as he toured with Christina Aguilera.


Justin Timberlake previously dated Britney Spears and Cameron Diaz had been in relationships with fellow movie stars Matt Dillon and Jared Leto.


In July 2004, Justin Timberlake filed a libel suit against the British tabloid News of the World after it claimed he'd cheated with model Lucy Clarkson, and in May 2005, Cameron Diaz sued U.K. tab The Sun for suggesting she'd had an affair with Shane Nickerson, the producer of her MTV adventure show Trippin'.

Cameron Diaz is reportedly close to agreeing a settlement in her $30 million lawsuit against an American magazine that accused her of cheating on Justin Timberlake.


The National Enquirer last year claimed that Cameron Diaz was having an affair with Shane Nickerson, the married producer of her Mtv show Trippin'.


It printed pictures of the pair leave a recording studio and hugging.


Cameron Diaz immediately sued for slander and libel, accusing the tabloid of turning "an innocent, insignificant and non-memorable occurrence involving two co-workers and friends (into) a sensationalistic, scandalous and accusatory story which was completely false."

Justin Timberlake says he will marry Cameron Diaz in 15 years from now.


Justin Tiberlake - who was appeared on 'The Ellen DeGeneres Show' on Monday - has denied the couple are engaged at the moment but insists they will get married eventually if they stay together.



When Ellen DeGeneres asked Justin Timberlake:

should I get a bridesmaid dress now or not?

He replied:

You know what? Go ahead and reserve one.

The only thing is you'll have to stay the same size for the next 15 years.
