X17 XCLUSIVE - Robbie Williams Ready To Wed -- With Pre-Nup In Place!

Preparations are underway at Robbie William's Beverly Hills mansion, where workers are setting up for a wedding reception after Robbie and American actress Ayda Field wed in a secret location.

X17online spotted tents being set up and equipment being loaded into the property just this morning.

Earlier this month Robbie, who is one of the richest music men in England, apparently finalized a pre-nuptial agreement that would limit Ayda Field's access to his $130 million fortune if things don't work out.

But today I'm sure the couple is focused more on what happens when they say "I do!" After plans for a wedding in Catalina were scrapped, guests are waiting to find out where to head for the exchanging of the rings, reports the The Sun.

"He will have a handful of very special people including his manager Josie and his best friend Jonathan," says a source. "The couple will tie the knot and then enjoy a small reception at his house. He does not want a big circus and just wants a private affair behind closed doors."

Although if these preps are any clue, "private" doesn't necessarily mean unfancy! But for Robbie Williams would you expect anything less?
