Michelle Williams and Busy Philipps walked the red carpet on Tuesday.

The actresses and longtime pals attended the Los Angeles premiere of their movie "I Feel Pretty" at the Westwood Village theater in Westwood.

Williams and Philipps were all smiles as they posed for photos together at the event. Williams wore a black dress with a belted waist and plunging neckline, while Philipps sported new, pink hair and a strapless, embellished gown.

"My girlfriend is a dream in real life and in the movie @ifeelpretty," Philipps said of Williams in an Instagram post.

"I hope you guys see this movie this weekend! We love it and we hope you do too."

"I Feel Pretty" stars Williams, Philipps, Amy Schumer, Emily Ratajkowski, Rory Scovel and Aidy Bryant, and opens in theaters Friday.

The movie follows a woman (Schumer) who wakes up from a fall with new-found confidence.

Williams and Philipps previously co-starred as Jen Lindley and Audrey Liddell on The WB series "Dawson's Creek."
