VIDEO: Sarah Jessica Parker Talks Twins, Mole With David Letterman

This holiday season, Sarah Jessica Parker is down a mole, but up two beautiful babies, the actress told David Letterman on the Late Show Tuesday night.

Parker showed off a picture of her twins, Marion and Tabitha, who she said, "are about as un-identical as twins can be."

Said Parker of the kids, who were born via surrogate mother on June 22: "They will be 6-months at the end of this month and they are physically, intellectually spiritually, geographically, politically, ideologically and religiously as different as two small 6-month-olds could be."

Parker and her hubby Matthew Broderick also have a 7-year-old son, James Wilkie.

Parker also discussed getting rid of her trademark mole, something she said she just wanted to have done.

"I had six free days where I could be bloodied and scabbed, and no one would care," she said, adding the procedure was administered by her brother-in-law, who she said is "a very respected plastic surgeon."

She said a woman came up to her on the beach after the procedure, and yelled at her about losing the signature mole.

"My mole is my signature ... isn’t my brain my signature?” Parker said. “Can you put it back on?!?"

Sarah Jessica Parker stars sans mole in the new romantic comedy Did You Hear About The Morgans? with Hugh Grant starting Friday.
