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. However, these speculations were debunked when Bridget’s real identity was revealed. Sources went to dig and reported that the expectant mother doesn’t just attend glitzy parties she was described as “independent and independently wealthy” and not after Kevin’s wealth.

They have been severally photographed holidaying on scenic destinations. Years after they got married, the couple were spotted at Le Cirque drinking a 1996 Cheval Blanc while eating an ultra-choice Japanese pure-bred beef; the beet was said to have come from Bill’s Colorado-based 7X Ranch.

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.

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.

Rather, he is part of the real estate industry, working at Frankel-Bell Realty as an agent. Nothing much is known about Liam as he loves to live his life away from the limelight.

After Bridget tied the nuptials with Bill in 2005, she became a second-time mother to her only daughter, Kaitlin Koch, in 2006.
