Alec Baldwin's Looking Years Younger, Thanks to New Marriage -- and a New Hair Color [POLL]

Is That New 'Do for the Last Season of 30 Rock?

Why is Alec Baldwin's hair all of a sudden several shades lighter, almost to the point of being blond? Is he just trying a new look, or is the hair part of a makeover for the upcoming seventh, and final, season of 30 Rock?

We don’t know the answer to that yet, but what we do know is this: the hair is definitely working for the Emmy-winning actor. That, and his new marriage to Hilaria Thomas, have the actor looking happy, healthier and younger than he has in years.

Baldwin and Thomas debuted his new locks this week as they helped kicked off the U.S. Open tennis tournament in New York, including a Monday night charity event for USTA Serves, VanityFair.com reports.

Baldwin was dressed in tan pants, a plain white shirt and jacket, and it was the hair that stole the show, helping give the always handsome actor -- who the New York Post used to call "The Bloviator" because of his tendency to rant and the extra weight he had put on since his big-screen leading man days -- his freshest look in a long time.

Meanwhile, in other Baldwin news, those rumors that he and Thomas, who he married earlier this summer, are expecting their first child together turned out to be false. Apparently. For now.

The 28-year-old yoga instructor and the 54-year-old Baldwin sparked the rumors last weekend when Hamptons partygoers thought guest Thomas was sporting a baby bump, but E! Online reports Thomas is not expecting.

Again, we'd add a "yet" onto that.

Baldwin's final season as network executive Jack Donaghy on 30 Rock kicks off on Oct. 4 on NBC.
