NEW YORK — This much is clear -- the Obama girls are welcome on the set of "Hannah Montana."

But any talk that 10-year-old Malia and seven-year-old Sasha are likely to appear on the popular Disney Channel show seems to be just that - talk. And it's been mostly from Billy Ray Cyrus, father of "Hannah Montana" star Miley Cyrus.

He told "Access Hollywood" on Monday that the young daughters of president-elect Barack Obama and his wife, Michelle, would "probably" be appearing on the show.

He says: "The invitation is there."

The 47-year-old country singer said he expected the guest shots to take place next spring.

"Maybe something might happen around then," he said.

The Obama camp could not confirm any invitation, apart from a statement released Tuesday by the Disney Channel saying: "We're pleased that Malia and Sasha are fans and, as long as their parents say it's OK, they are invited to the set of 'Hannah Montana' and all Disney Channel shows, for a guest role or a visit, anytime."
