Rumours that Tom Cruise and Katie Holmes are going to tie the knot this week are hotting up.

Speculation has been sparked after several huge tents and outdoor chandeliers were spotted being erected at the Scientology Celebrity Centre, in California.

The 'Mission: Impossible III' actor proposed to the former 'Dawson's Creek' star - who gave birth to their first child, Suri, in April - in Paris last year.

A source is quoted by website MollyGood.com as saying: "I live in Beachwood Canyon, right up the hill from the Scientology Celebrity Centre, and there is most definitely something going on soon.

"I know that Tom and Katie have been there twice in the last week and now the centre is covered in tents and outdoor chandeliers. Huge planters are in the street to prevent anyone driving too close."

Meanwhile, it has been claimed the couple's hairstylist, Oscar Blandi, has been booked "all weekend" for them.

The increased speculation comes just days after Tom, 44, and Katie, 27, announced they will tie the knot soon.

The 'Top Gun' star's spokesman Paul Bloch said: "As far as I know, the plans are for late summer, maybe a bit later."

It has been claimed Katie's parents will not attend the nuptials if the pair wed in a Scientology ceremony.

Martin and Kathleen Holmes are both devout Catholics and reportedly do not approve of Tom's devotion to the bizarre sci-fi cult.
