#21 Heather Mills & Paul McCartney: $3 Million
Getting married to a music legend can have lots of perks, including an unforgettable wedding! The ex-Beatles bandmember got hitched to Mills in a $3 million wedding, which was kept private from the prying eyes of the Paparazzi.
The celebrations took place in 2002 in a stunning castle located in Glaslough, Ireland. Sadly, the two parted ways in 2008, which lead to a settlement that is supposed to have cost even more than the wedding itself!
