Alec Baldwin has good taste!

After popping the question to Hilaria Thomas this weekend, the 30 Rock actor's yoga instructor fiancee couldn't wait to debt her new engagement bling.

Thomas, 28, stepped out in NYC on Monday bundled up in an all-black outfit — that only made her platinum diamond sparkler stand out even more!

Baldwin's rep confirmed that the actor, who turns 54 on Tuesday, is giving marriage a go with his girlfriend of less than a year.

"Yes, it's true!" Baldwin's rep tells Us Weekly. "Alec proposed to Hilaria this weekend and we're all excited for the newly engaged couple. Alec's birthday is tomorrow. Great way to celebrate!"

Baldwin has stayed single since his infamously bitter divorce from Kim Basinger in 2002, but his family tells Us that Thomas is the kind of woman he needs to settle down.

She is "very humble, very sweet, very down-to-earth and very charming," Alec's brother Stephen Baldwin, told Us in October. "I'm glad that they're into each other. Alec's a lot calmer and a lot happier."
