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.
