Fergie is reportedly pregnant with twins. The "Big Girls Don't Cry" singer - who married "Transformers" star Josh Duhamel in Malibu on Saturday - allegedly told bystanders at Los Angeles International Airport she is already expecting new additions to her family.

Asked if she was planning on having children in the near future, Fergie said: "I'm pregnant with twins."

Fergie and her fiance Josh Duhamel have had a joint bachelor/bachelorette party Thursday night. The pair - who are set to tie the knot in a lavish ceremony in Los Angeles Saturday - partied with 75 friends at new Santa Monica club Dakota Lounge.

The couple decided to go against tradition and celebrate their upcoming wedding together so their friends could meet each other before the ceremony.

With their wedding day fast approaching, Fergie is busy crunching and tightening her body to transform herself into a glamorous bride. Fergie is set to walk down the aisle with "Transformers" actor, Josh Duhamel.

Fergie is said to be working out every day to lose weight. Fergie admits it hasn't been easy to shed the pounds she gained for her role in the upcoming movie "Nine." Her workout routine includes hiking and sit-ups.

Fergie will marry actor Josh Duhamel in January. The 33-year-old "London Bridge" singer and the "Transformers" star will tie the knot in Southern California over the second weekend of January.

It has been claimed many of Fergie's "Nine" co-stars, including Kate Hudson, Nicole Kidman, Penelope Cruz, Sophia Loren, Marion Cotillard and Daniel Day-Lewis, will attend the ceremony.

Fergie has gained 13lbs for her role in musical movie "Nine." The Black Eyed Peas singer - who stars alongside Nicole Kidman in the upcoming film - indulged in calorific treats to put on weight for her role as prostitute Saraghina.

She said: "I've actually gained 10 lbs! No, really - for the film, 'Nine.' Actually, 13 to be exact. I ate everything! Fish and chips. Everything fried - things I don't normally eat."

Fergie and Josh Duhamel are getting married in June 2009. The couple - who have been engaged since last Christmas - have finally started planning their nuptials, and are reportedly thinking of a summer ceremony.

A source close to the pair said: "Fergie has just started interviewing wedding planners. She's also working with Chanel designer Karl Lagerfeld on getting her fantasy gown."
