After the news of Bridget’s pregnancy started making the rounds, many fans of the Hollywood star were of the opinion that the American socialite might be out to get a share of the actor’s massive fortune.

The couple has a Palm Beach, Florida home sitting on a 42,000 square foot oceanfront mega-manse where they threw a lavish party in 2012 to commemorate Bridget’s birthday. Bill seems to be the kind of man that makes his wife’s every wish come true; he actually brought Roar singer Katy Perry to perform at the party.

Another lavish gift he purchased for Bridget was a double two-foot-tall silver centerpiece. According to history, the centerpieces were made by Queen Victoria’s silversmiths in 1860. The property was bought at the price of $240,000 from an English dealer. The couple showcases this at their dining table.
