Justin Timberlake on Cameron Diaz: "We're Not Engaged"  9/6/06

Sexyback singer Justin Timberlake has rubbished reports he is engaged to his longtime girlfriend Cameron Diaz.

The singer helped kick off the fourth season of US talk show The Ellen DeGeneres Show by performing in New York City's Central Park, which was broadcast on Monday (04SEP06).

After the performance, DeGeneres brought up "the rumor that you and Cameron are engaged".

Timberlake tried to defer, asking the host how she could put him on the spot in front of the crowd of 10,000 people.

When DeGeneres asked him where things stood between the couple, he said of recent press reports, "Funny thing, one week we're getting married, one week we've broken up.

"I can't keep up with it."

When DeGeneres persisted and asked if the couple were engaged Timberlake said, "We're not engaged."

He then added jokingly, "She hasn't given me a ring. I've waited for her to get down on one knee and ask."
