The 23-year-old singer is in a hurry to marry her boyfriend, because the couple is expecting a baby.
A Simpson family friend revealed this news to People. The source also stated that the wedding would take place at a friend’s house in La Jolla, California in May.
Wentz denied the rumours that his fiancée was pregnant. In fact, he accused the tabloids of being on a "witch hunt," as soon as the engagement was announced in Hollywood.
Simpson was vague when questioned about the pregnancy rumours. "Some things you want to keep personal," stated the star.
