The 31-year-old, who gave birth to daughter Maxwell Drew Johnson on May 1, is yet to set a wedding date but she is hoping to tie the knot later this year, reported a website.
"I can't wait. I want to feel really great in a wedding dress. It's going to be one of the most amazing weddings of all time. I'd love to do it before the end of this year, but you just never know. I haven't set a date yet," she said.
Simpson also said she thinks she is doing a good job at motherhood. "She's my career at the moment. I know I was always meant to be a mom and I think I'm doing a really good job. I'm the most aware I've ever been," she said.
