Sarah Jessica Parker Is So Vein

... as in the bulging vein in her bicep!

Sarah Jessica Parker is showing off her sculpted arms while on the set of her latest movie I Don't Know How She Does It. The movie is due out next month, so they must be doing last minute re-shoots. Yikes!

The flick, filming in New York, also stars Olivia Munn, Christina Hendricks, Pierce Brosnan, Greg Kinnear, Gossip Girl's Jessica Szohr and Cougar Town's Busy Phillipps.

In the current issue of Marie Claire, SJP tells the mag:

“I never wanted to be a celebrity; I never wanted to be famous. And in my daily life, I work really hard to not trade on it in any way. I am so desperately worried about anybody saying, ‘She cut in line’ or ‘She took our table’ or She got out of jury duty’ or ‘She doesn’t do her own grocery shopping."

Now what would Carrie Bradshaw think of that statement? See Sarah's co-stars Olivia Munn and Busy Phillips on set in NYC ... after the jump.
