After weeks gruelling promotional tours and a seven hour flight, you couldn't blame Sarah Jessica Parker and Kim Cattrall for wanting a long lie down.

But as the Sex And The City 2 co-stars jetted into London this morning following an overnight flight from New York, they looked stylish and cheery.

While mother-of-three Parker, 45, went for a casual look in skinny jeans, grey jumper and ballet bumps, Cattrall, 53, looked smart in a pink cowl neck dress and strappy heels.

The two stars arrived in the British capital today ahead of Thursday's star-studded premiere of Sex And The City 2.

They are scheduled to be joined by co-stars Cynthia Nixon and Kristin Davis, as well as Parker's on-screen husband Chris Noth.

The two actresses boarded a flight at JFK last night just hours after Parker appeared on The Late Show With David Letterman and Cattrall on rival talk show Late Night With Jimmy Fallon.

While the London premiere comes a few days after the world premiere in New York, the first film was a different story.

Cheery: Liverpool-born Cattrall looked pleased to be back in her birth country

Many New Yorkers threatened to boycott the first Sex And The City film after the world premiere took place in London - despite the film and TV series being set in Manhattan.

Producers apologised, insisting it was logistical and scheduling conflicts being behind their decision to debut the movie in London.

Meanwhile, Parker was left red-faced on Letterman last night after she described her husband Matthew Broderick as 'average.'

The actress feverishly backtracked after making the gaffe, insisting the only place he was average in was height.

The mother-of-three made the unfortunate slip when she admitted her seven-year-old son James Wilkie was 'on the diminutive side'.

Parker appeared on the late night show to promote the new Sex And The City sequel, which had its world premiere in New York on Monday night.

Wearing a zebra-print dress, white blazer and striking turquoise and black peep-toe heels by London-based designer Nicholas Kirkwood, Parker looked toned as she signed autographs for fans outside the Ed Sullivan Theatre, where the Late Show is recorded.

Parker made the gaffe when she was discussing her son James and his education at a 'progressive' school.

Parker explained her son was one of the oldest in the class, which helped him socially because he isn't as tall as his classmates.

'He is, for the moment, more on the diminutive side. Some might call it a Napoleon complex, it (his age) gives him some (confidence) because he is so mature. He's a brainiac... well I think so, naturally.

'He's not quite tiny - that's on my husband's side - well, actually Matthew is average... not in personality or in intellect.... no, no, no, no, no.

'Let me clear this up. For the record, not in personality, intellect, charisma, talent, genuine likeability, well the list could go on and on.

'Anyway he's average in height as I understand so the odds of our son being average in height and weight is perhaps promising.'

The Ferris Bueller's Day Off star is 5ft 8, while his wife is 5ft 3.

After Parker claimed her son had already been accepted to the famous Massachusetts Institute of Technology, Letterman quipped: 'Even with an average father.'

Parker shook her head and said: 'How am I ever gonna fix this?'

Togetherness: Parker and Broderick, pictured at the Sex And The City 2 after-party on Monday night, celebrated their 13th wedding anniversary last week

The couple, who celebrated their 13th wedding anniversary last week, attended both the Sex And The City 2 première and after-party together on Monday night.

Her chat show faux pas wasn't the first time Parker embarrassed her husband - she famously forgot to thank during her rambling acceptance speech at the Emmys in 2004, despite mentioning dozens of other people.

Meanwhile, the National Media Council (NMC) in Dubai has banned the film in the United Arab Emirates.

Censors decided the film was inappropriate for Emirates audiences due to the 'improper' language and sex scenes and controversial cultural clashes between the Western and Muslim women.
