It's a Destiny's Child reunion!

Beyonce made an appearance at her BFF Kelly Rowland's 35th birthday party on Saturday night, which was held at the Sunset Tower Hotel in West Hollywood, California. The two were joined by Michelle Williams, making the Destiny's Child reunion complete!

Check out the three ladies looking closer -- and fiercer -- than ever, in a cute pic Rowland Instagrammed on Sunday.

It was also a Knowles family affair at Rowland's big birthday bash. Beyonce's mom, Tina Knowles, shared a few black-and-white pics from the party as well, including one with Beyonce, and one with her younger daughter, singer Solange Knowles.

The birthday girl even paid homage to Beyonce's now-famous pose from the "Formation" music video, giving two middle fingers to the camera and rocking a huge eye-covering hat.

#HAPPYBDAYTOME," the mother-of-one Instagrammed.

Presumably, Beyonce dropped by Rowland's party after her date night with her husband, Jay Z, at the Clippers vs. Warriors game on Saturday, since she's sporting the same fierce outfit.

Of course, Rowland's birthday celebration isn't the only time the Destiny's Child ladies reunited recently. The trio performed together last March, when Beyonce and Rowland joined Williams for her planned appearance at the 30th Annual Stellar Gospel Music Awards to sing "Say Yes," a song that earned Williams a Stellar Award nomination.

"Friendship is the foundation of everything we do -- no drama," Williams told ET at the time. "People are looking for drama but we have none to give you. It's literally friendship and sisterhood and respect."
