Ashlee SimpsonJessica Simpson has revealed she’s planning to spoil her forthcoming niece or nephew after sister Ashlee Simpson-Wentz gives birth later this year.

Jessica told E! recently: “I’m going to spoil the kid rotten, that’s for sure.

“I think my sister’s going to be pretty strict, actually, because she’s been so good throughout her pregnancy.”

She added that it’s strange seeing her young sibling pregnany: “She’s just such a woman. I’m like, ‘Oh, my gosh - what’s happened to my sister?’”

Ashlee married boyfriend and dad-to-be Pete Wentz in May this year, shortly before the couple announced the pregnancy.
