The trio are not known to be friends, but Hollywood's a small town, and they're sure to have crossed paths before.

In any case, it appeared to more than a coincidence that Paris was in attendance at the Cut restaurant in Beverly Hills where the world's most famous Scientologist and his young wife were dining.

Hollywood's first couple were said to have spent three hours at the restaurant, but they emerged alone, and Paris was seen leaving separately.

Meanwhile, Katie sent her best wishes to husband Tom's ex-wife Nicole Kidman following the news of her pregnancy.

The salutations came just weeks after Katie declared Nicole's adopted children 'call me mom'.

Katie spoke of Nicole's pregnancy at the world premiere of her movie Mad Money on Wednesday night - her return to the big screen after a three-year absence.

Nicole, who divorced Tom in 2001, confirmed this week she was expecting her husband Keith Urban's first child in the summer.

Katie enthused: "I'm so happy for her. It's wonderful."

Her support followed last month's controversial comments about Tom and Nicole's adopted children Isabella and Connor.

Katie said: "His first two children are incredible, really smart and kind. They call me 'Mom'."

Mad Money marks Katie's return to movies after a long absence.

She was last seen in Thank You For Smoking in 2005 and took time out of her film career when she first started dating now-husband Tom Cruise in April 2005.

Following the birth of daughter Suri exactly a year later and marriage in November 2006, the 29-year-old finally went back to work last year in the crime caper Mad Money.

After years of supporting her husband on the red carpet, it was Katie's time to be the centre of attention at the world premiere of Mad Money.

Shortly after arriving, Katie called on Cruise to fix her bejewelled dress before she faced the paparazzi.

Echoing her close pal Victoria Beckham's style, Katie wowed the paparazzi in a stunning strapless puffball gown outside Mann's Village Theatre.

While Katie looked sensational on the red carpet, her husband Tom committed a fashion faux-pas in a midnight blue velvet jacket.

Katie looked thrilled to see her co-stars Diane Keaton and Queen Latifah at the star-studded bash.

In the film, the three women play employees of the Federal Reserve Bank who plot to steal money before it is destroyed.

The actress's next movie The Other Side, which she was expected to begin filming two months ago, has been delayed due to the current writer's strike.

Katie is set to play a student who falls for fellow Scientologist Giovanni Ribisi's character in the comedic fantasy movie.

Meanwhile, Katie has denied reports she is planning to run the Boston Marathon in April.

The reports emerged after Katie's completion of the New York marathon in November.

Her spokesperson said: "Katie Holmes is not running in the Boston Marathon."
