Timberlake to sing at DeGeneres wedding

Justin Timberlake has told US chatshow host Ellen DeGeneres that he wants to sing at her wedding to Portia de Rossi.

Taking advantage of Timberlake's appearance on her show, Ellen suggested that she and de Rossi could marry with him and actress Jessica Biel.

"We could have a double wedding. We could do it together," she said.

Timberlake replied: "I don't know about all that. You know, I'll sing at your wedding."

DeGeneres accepted Timberlake's offer and said he could write a song using her and De Rossi's notebooks as inspiration.

"I will put it on music. It'll be amazing," Timberlake said.

DeGeneres announced last week during a taping of her talkshow that she would marry her actress girlfriend de Rossi.

Rumours surfaced earlier today saying that Timberlake is planning to wed Biel.
