Kate Middleton has visited Warner Bros. studios with Prince William and Prince Harry on Friday where they learned about "Harry Potter."
The royal trio attended the inauguration of the famed movie studio in Leavesden, Hertfordshire- the home of "The Making of Harry Potter" exhibit that includes props from the film.
The Duke and Duchess of Cambridge as well as Prince Harry also visited the studio's Great Hall, saw a special effects demonstration on Diagon Alley, and played with wands in the "Harry Potter" inspired Gryffindor Common Room, according to Daily Mail.
Children and adults from the charities supported by the royals joined them for Friday's tour of the studio.
About six months along in her pregnancy, Middleton wore a black-and-white polka dotted dress paired with a black coat and suede heels as she displayed her growing baby bump.
Known for her fashion choices, Middleton purchased the flowing dress from Topshop, according to the Daily Mail.
Other highlights of the royals' visit included Princes William and Harry sitting in the Batmobile- the vehicle used during the filming of "The Dark Knight Rises."
"Does it come with a baby seat," father-to-be Prince William reportedly quipped.
Friday marked the fourth outing Duchess of Cambridge had been spotted along this week. Among her recent royal engagements was an inspection of the Queen's Scouts at Windsor Castle on Sunday as well as an evening reception at the National Portrait Gallery.
Meanwhile, the Duke and Duchess of Cambridge are expecting their child in July. Discussing her pregnancy with a fan during a past engagement, Middleton revealed that the baby was kicking.
"She said, 'Yes, it is. Very much so,'" revealed Bobbie Brown to Us magazine about Middleton's visit to Grimsby, England last month.
Furthermore, insiders revealed that Middleton's pregnancy has resulted in unusual cravings. The expectant mother reportedly acquired a new penchant for lavender shortbread during the early stages of pregnancy, according to The Sun.
"A lot of women develop cravings during pregnancy and Kate is no exception," a source told the publication. "She has got a real taste for these biscuits."
The unusual sweet treat combines the buttery cookie with the aromatic herb, resulting in one of today's most posh desserts. Additionally, lavender is believed to lend pregnant women relief from morning sickness- making it a perfect snack for the Duchess, who suffered from the condition early on in her pregnancy.
