Just when you thought this summer’s weddings couldn’t get anymore outrageous, leave it to a Croatian heiress to steal the show! Petra Ecclestone, daughter of Formula One racing boss man, spent a cool $5 million this weekend on her wedding in the same castle where Tom Cruise and Katie tied the knot.

The bride danced to Eric Clapton and the Black Eyed Peas in a custom-made $130K Vera Wang gown; Alicia Keys played the rehearsal dinner. If the name sounds familiar, it’s because Petra recently bough Aaron and Candy Spelling’s former 90210 address for $85 million. I gather she is NOT a bargain shopper!

In other celeb wedding news, VMA drag-artist Lady Gaga is rumored to be planning a wedding ceremony to longtime off/on boyfriend Luc Carl in a venue big enough to hold *gulp* 18,000 people. Of course, the fashion choices of this mega star will dominate everyone’s attention, so Paddy Power is taking bets on who the designer will be. Check it out .

Should this monster wedding proceed, you can bet Gigmaster’s will be trend-watching for all of the musical details sure to rival the Grammy’s.
