Hilaria Baldwin showcased her baby bump with Alec Baldwin on the Mean Girls red carpet!

Alec and Hilaria Baldwin are currently expecting their fourth child together, a baby boy! The couple hit the red carpet this past week on Sunday, attending the opening night of Mean Girls on Broadway.

Hilaria Baldwin, an esteemed yoga instructor, attended the event showing off her growing baby bump, wearing a lovely multi-colored pastel striped dress and cozying up to Alec on the red carpet, who sported a simple black suit sans tie.

Mean Girls on Broadway is based on the 2004 hit film Mean Girls and saw many other stars in attendance such as Jimmy Fallon, Busy Philips, and the film's writer, Tina Fey. The mother of three finished off her stunning look with wavy brunette locks that parted at the center, with a soft glammed makeup look that complimented her gorgeous soft pink lip.

The couple got married back in 2012, and are expanding their family. Their newest addition will be a third boy, joining siblings Carmen, Rafael, and Leonardo, who the couple had only one year ago. Hilaria wasn’t the only one looking stunning on the red carpet. The shows creator Tina Fey looked absolutely jaw-dropping in a white blazer mini-dress with wavy brown locks for the evening's event.

Busy Phillips, who also showed her support for the show Sunday night, showed up in a pink blazer, blue jeans, and bolo tie for a glam western feel. The Broadway show has been the talk of the town lately after first running at the National Theatre in Washington, D.C and again at the August Wilson Theatre in New York City before officially opening Sunday night.

There are has been much talk of a potential Mean Girls reunion starring cast members Lindsay Lohan, Rachel McAdams, and Tina Fey herself. However, fans will have to settle for it on Broadway for now! With what is expected to be an amazing show, we’re happy to see stars such as Hilaria Baldwin glowing on the red carpet. We’re sending our best to her and Alec on their fourth child!
