Kristin Davis was driven "crazy" by her child co-stars
The 45-year-old actress - who reprises her role as mother-of-two Charlotte York Goldenblatt in the movie sequel - admits she didn`t need to act when showing her character`s strain at caring for two young children.
She told BANG Showbiz: "I didn`t have to work myself up for those scenes. Those kids were driving me crazy!"
Although Kristin struggled with some of the family scenes in the movie, she insists she is always happy to undertake whatever is asked of her by director Michael Patrick King.
Speaking at the UK premiere of the movie in London`s Leicester Square last night, she added: "I would never refuse to do anything that Michael asked of me, he knows the characters so well that whatever he did would be for the good of the film."
Joining the film`s stars Kristin, Sarah Jessica Parker, Cynthia Nixon and Kim Cattrall at the premiere, were a host of other famous faces, including Kylie Minogue, Emma Roberts and Emma Bunton.
