The 31-year-old, who gave birth to daughter Maxwell Drew Johnson May 1, hasn't set a wedding date yet, but she is hoping to tie the knot later this year.
"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," showbizspy.com quoted Simpson as saying.
"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 added.
