Dolly Parton is launching a two-year, $10 million expansion of her country theme park in Pigeon Forge, Tenn., in the mountainous region where she was born.

The plan will allow Dollywood to operate on a year-round basis beginning in the spring of 1990, the entertainer announced Friday.The expansion includes shops, restaurants, a celebrity theater and a new museum that's nearly double the size of the current one.

Parton, 43, opened the park in 1986 near the Smoky Mountain National Park in East Tennessee. The flamboyant singer grew up in nearby Sevierville in a two-room mountain shack.

"I think it would be great for the business community here if we could help make the Smokies a year-round resort area by doing special things in the wintertime, because winter in the Smokies is gorgeous and really pretty mild in terms of weather," she said in a statement.

Parton is celebrating her 25th year as an entertainer. She has starred in several movies including the hit "9 to 5," was host of a television series and recently released her 50th album, "White Limozeen."
