All is not peachy keen Manolos and a Cosmo swilling love-in as feuding SEX AND THE CITY stars explode.

Stars Sarah Jessica Parker, Kim Cattrall and Cynthia Nixon admit their rivalry, confirming longstanding rumors they frequently bitch and argue while shooting the sequel yet insist they’re are still good friends.

"When you’re on set, you’re working 90-hour weeks, you’re never home, you’re exhausted," SJP confessed. "There are times when all of us have been sensitive and sometimes feelings get hurt. But I don’t have any regrets about how I’ve treated people."

Cynthia chimed in, "It hasn’t always been smooth sailing. But the idea that we’re somehow adversarial is ludicrous."

And Kim  admitted occasional bickering and kvetching, will rear its ugly head: "Nineteen-hour workdays are stressful, whether you’re driving a truck, working in a coal mine or on a set and trying to be your brightest at 4 o’clock in the morning.

"But there’s a camaraderie that happened through all of that."

Just life during wartime in the battle of the sexes waged by strong-willed actresses.
