All eyes on Katie Holmes in a low-cut dress as husband Tom Cruise is honoured by Jewish human rights organisation

It can be difficult to stand out when your husband is a world-famous action movie star.

But last night Katie Holmes managed to take centre stage as Tom Cruise was being honoured by the Simon Wiesenthal Centre by turning up at the event in a low-cut dress which drew attention to her cleavage.

The 32-year-old actress looked stunning in the black dress with green sash, which she teamed with black sandals, as she posed with Cruise outside the event.

However, it was inside the event that Holmes really stood out from the crowd, as she glowed while applauding the honorees at the ceremony.

The couple were also accompanied by Cruise's 16-year-old adopted son Connor as the Mission: Impossible actor was presented with the Humanitarian Award - the highest honour bestowed by the Simon Wiesenthal Centre, a Jewish rights organisation which also educates people about the Nazi Holocaust.

Cruise, who played a German military officer who planned an assassination of Adolf Hitler in the 2008 film Valkyrie, was honoured for his support of the organisation throughout his life.

Absent from last night's ceremony was the couple's five-year-old daughter Suri, who is perhaps too young for such an occasion.

Despite reports that she and her husband are planning to have more children, Holmes recently insisted that she is happy with the size of her family.

She also said that Cruise and ex-wife Nicole Kidman's adopted children Connor and 18-year-old Isabella get on incredibly well with Suri.

She said: 'They're great kids, a great brother and a great sister to Suri, and she's a great sister to them. It's not, "This is stepmotherhood and this is motherhood".

'I'm not worried about it (having another baby). She's got really good friends and great cousins, so I feel happy about it.

'We have a really busy household, and it's really fun and fulfilling. There's always something going on.'
