Billy Ray Cyrus has played a variety of onscreen roles, including a caring doctor in the popular TV series Doc and Daniel Burton, a crusading father in the Hallmark Channel movie Christmas in Canaan. But one offscreen role that's not in the cards, at least not yet, is the part of "grandfather."

Back in August, it was reported by several outlets that Billy Ray's son Trace and his fiancée, actress Brenda Song, were expecting a child after Brenda was spotted sporting a "baby bump."

But Billy Ray tells CountryWeekly.com that Brenda is not pregnant. "I'm not going to be a grandpa yet," he says.

"We don't have any [grandchildren] in the can right now. In today's world," Billy Ray adds, "one rumor gets loose and before you know it—boom—everybody has the story."

Billy Ray notes that he was looking forward to being a grandpa at the relatively young age of 50. "I got real excited," he admits after he first heard the reports. "I think I'd be a great grandpa. I look forward to it one day."

Trace is the son of Billy Ray's wife, Tish, and was adopted by Billy Ray after he and Tish married. Billy Ray is also set to star in a sequel to Christmas in Canaan titled Christmas Comes Home to Canaan, which premieres on the Hallmark Channel Dec. 17.
