(Cover) - EN Showbiz - Tori Spelling reveals that she is an extremely active mother at the moment.

The 39-year-old actress and reality star is expecting her fourth child with husband Dean McDermott after falling pregnant soon after the birth of their 11-month-old daughter Hattie.

Tori looks to her brood for fun and support in preparation for her new arrival.

"I've actually just been doing a lot of stuff with the kids because, with a fourth baby, I still want to make sure they feel completely involved," she told the American edition of OK! magazine.

Tori's eldest children, Liam, five, and Stella, four, are helping their mother style their future sibling's room. They also have a hand in choosing the clothing the baby will wear.

"They've been helping with the nursery, and they went and picked out outfits for the baby," Tori explained.

"We don't know if it's a boy or girl, so I picked out a girls' outfit and a boys' outfit."

Tori is due to deliver the child in September. (C) Cover Media
