Jessica Simpson is releasing her own line of lingerie.

The singer - who will release her debut country album this summer - has already launched successful handbag, footwear, sunglass and swimsuit lines, and is hoping her Jessica Simpson's Intimates underwear will be a hit.

She said: "I like different lingerie for different occasions. I think that's the best thing about it. You can feel sexy or girly depending on your mood."

Jessica - who is dating American football star Tony Romo - promised to include a range of 'shapewear' in the line, to help women combat visible panty lines under their clothing.

Jessica Simpson's Intimates will be made up of bras, panties, nightwear and daywear, and will be available to buy in US department stories and online by next spring.

Meanwhile, Jessica's father Joe has denied reports he has a controlling influence over the singer and her younger sister Ashlee.

He said: "The media says that I try to plan everything. But Ashlee and Jessica don't call me and ask me. They call me and tell me!"

Joe also said reports of him coming between Jessica and Tony were completely untrue, adding to Us Weekly magazine: "Jessica is as happy as I've seen her in years. Tony is a great guy. I love him to death. He's just a good kid."
