Allen, Lambert hint at future collaboration

American Idol stars Kris Allen and Adam Lambert have hinted at the possibility of recording a track together.

The pair, who are about to begin a tour of the US with their fellow finalists, told E! Online that they are interested in a future collaboration.

"It could happen. Maybe we'll write a song on the road," said Lambert, who recently signed a major record deal.

Allen, who was crowned the winner of this year's competition, added: "We have to figure it out, but yeah, we should do it."

The 50-city American Idol summer tour kicks off in Portland, Oregon, on July 5.
