Melbourne, May 13 : Hannah Montana star Miley Cyrus could record a duet with John Travolta, the actor's wife Kelly Preston has revealed.

Preston disclosed the news at the Step Up Women's'Network's Inspiration Awards luncheon at the Beverly Wilshire Hotel, May 12.

"Johnny may sing with Miley," the Daily Telegraph quoted Preston as saying.

Travolta and 15-year-old Cyrus are both voicing characters in the upcoming animated flick Bolt, and he and his wife had first met her when she was opening for Cheetah Girls during their concert tour about two years ago.

"We (now) know Miley very well," Preston said.

She further mentioned that she has not seen the teen sensation's Vanity Fair shoot, but knows that she's a sweetheart.

"All I know is that I know her personally and she's a really good girl with a great head on her shoulders," she added.
