Jessica Simpson will get married this year

London: Singer-designer Jessica Simpson insists that she will get married to her longtime partner Eric Johnson, with whom she has two kids, within this year.

The 33-year-old also said that she did not understand why people doubt her marriage with her fiance.

"People ask me every day if I`m getting married. I`m like, `I`m engaged, of course I`m getting married`!" she said.

The couple have a 20-month-old daughter, Maxwell, and six-month-old son, Ace, and believes he is the perfect man for her because they have already been through a lot together.

"He`s put up with me and all my hormones for the two and a half years that I`ve been pregnant. He has seen me at my absolute worst but he hasn`t gone far away," she said.

"Eric is like a big-hearted big guy. He`s the best father. Maxwell is a daddy`s girl so she is obsessed with him. She definitely has him wrapped around her finger," she added.

Simpson revealed she has yet to set a date for her upcoming wedding. The actress and her fiance have postponed their nuptials twice since getting engaged in November 2010.
