***** Tori Spelling Is Expecting a Boy*****

Tori Spelling and Dean McDermott are expecting a baby boy, PEOPLE has learned exclusively. "We are thrilled to be having a son together," says Spelling, 33. "Little boys are a ton of fun. We love talking to him. We play tunes for him and watch him kick. He already loves the Dixie Chicks! We went to their concert and he kicked the whole time."

McDermott, 39, who has a son, Jack, 8, from a previous marriage, adds: "Now Jack will have the baby brother he's been wanting!" (This will be Spelling's first child.)

The boy will be given the middle name Aaron after Spelling's late father, legendary TV producer Aaron Spelling, who died in June. "Yes, his middle name will be Aaron," Spelling, who is six months pregnant, tells PEOPLE. "Dean and I feel it's the perfect way to honor the memory of my father."
The parents-to-be are still deciding on a first name.

The couple spent Sunday morning shopping for their baby's first clothes at the celeb favorite Intuition – where Spelling had ordered a hooded blue bath towel embroidered with the name Aaron. "When she saw the towel with her dad's name on it, she got a little emotional," says Intuition owner Jaye Hersh. "She said she was so happy they were having a boy so she could honor her dad. It means a lot to her."
The couple also bought a selection of onesies, booties, a baby food organizer and two diaper bags for mom and dad. "They are so excited to be parents," says Hersh. "It was the first time Tori was shopping for clothes for her baby boy, and they loved picking out little outfits for him. Dean was really into the clothes, and he carried all the packages out of the store. He's very protective of her."
