Katie Holmes has reportedly splashed out over $3,000 on sexy underwear for her wedding night with Tom Cruise.

The “Batman Begins” actress visited La Bra Lingerie, in West Hollywood, to buy a selection of racy lingerie for her soon-to-be husband - who she is set to marry on November 18 - including splashing out $1,000 on a special “bridal collection” set.

A source is quoted by website MSNBC as saying: “They weren’t all white - and they certainly weren’t virginal. But she’s a mother, so I guess that’s appropriate.”

The 27-year-old actress’ purchases included the Chantilly lace bridal collection with a bra that cost $440, a $340 thong, a garter belt for $220, and silk stockings that cost $95 - for a total of $1,190.

Katie also chose a silk nightgown with a matching robe trimmed with ostrich feathers that set her back $620, a lace bra with Swarovski crystals for $380 and matching thong with crystals for $175, as well as two sets of silk pajamas and matching robes at $425 each.

Meanwhile, Tom arrived in Rome yesterday (Nov 13, 2006) with a ten-strong entourage in preparation for the wedding next weekend.

The “Top Gun” actor was spotted arriving in a private jet at the Ciampino Airport outside Rome at 11:30 a.m. local time and was then driven to his hotel under police escort.

It has been reported that as Tom, 44, is a Scientologist and Katie was raised a Catholic they will have two marriage ceremonies.

But the “Mission: Impossible” star’s plans have run into trouble as he is a divorcee, and the Catholic church would not permit him to remarry in a Catholic ceremony.

But Tom’s representative, Arnold Robinson, said: “All of the proper and necessary arrangements are being made.”
