The secret was let out of the box in the Sex and the City 2 trailer.

In the long awaited sequel Carrie Bradshaw (Sarah Jessica Parker) runs into her ex Aidan Shaw (John Corbett) and suddenly she's having second thoughts about her marriage to Mr. Big (Chris Noth).

Today Noth tells Redbook that the sequel (which opens on May 27) is 'a great look into Carrie and Big's relationship and what marriage means to them.'

'No matter how long you've know someone, marriage changes some things in unexpected ways,' Noth says. 'And it's a learning process for Carrie and Big.'

Fans of the show can take heart too. Noth, 55, told Redbook: 'I'm more excited about this movie than I was about the first one. There's a lot of humor, which I love.'
