David Foster and Katherine McPhee – $90 Million

If there’s one thing Hollywood couples are good at, it’s proving that age simply does not matter. Take Katherine McPhee and David Foster, for example. Despite the 34-year age gap between them, they still managed to make their relationship work.

However, before the pair even entertained the thought of dating each other, Katherine and David worked together. The year was 2005, and Katherine was an aspiring singer fighting for her dreams on the set of American Idol. David, back then, was still married to his former wife, Yolanda Hadid. After years of having little to no contact with each other, fate brought the two back together, and this time, they made sure to seal the deal. The two got married back in June of 2019 and are now worth $90 million. David’s three older daughters are also quite charmed with the singer and have even given her credit for bringing their dad closer to them.
