Justin Timberlake has refused to duet with Britney Spears at the MTV Video Music Awards. Just recently, there was rumors about Britney Spears is to debut her comeback single at the awards ceremony and she will be duet with her ex-boyfriend Justin Timberlake.

A source said: “She’s planning it to be a big comeback performance and she wants it to be shocking.” But a reliable source close to Justin Timberlake told US Weekly magazine: “That’s totally, patently false.”

Meanwhile, singer-songwriter Ne-Yo revealed yesterday he has written material for Britney’s fifth album.

Ne-Yo told KIIS-FM radio host Ryan Seacrest: “Her new music is definitely up-tempo. She’s got to remind people why they love her in the first place. She’s got to get their minds off her personal life and back on the music.

“I have no idea what’s going on with Britney Spears right now. The last thing I heard is she was mad at me over some songs that were supposed to go to her.

“I wrote six to eight songs for Britney Spears, working really closely with her people. Then she goes and shaves her head and goes into rehab – and when that happened I lost all contact with her and the people at her label.

“I think it’s possible she can make a comeback. I heard a lot of the music. I definitely think she can do it.”
