Michelle Williams is seeing double — the singer was thrilled to “finally” meet the Oscar-nominated “Brokeback Mountain” actress of the same name in a video that has gone viral.

The big moment went down after the actress visited the singer to check out her show, “Death Becomes Her,” on Broadway Thursday evening.

“Y’all we had an amazing show tonight,” the Destiny’s Child alum, 45, said gleefully in an Instagram clip shared the same evening.

“The crowd was lit. We love lit crowds. And so I’ve got more things to sign. I always love to bring y’all in on my journey and of course I’ve got more, more, more of these!”

The “Survivor” singer held up photos of the “Shutter Island” actress, which had been erroneously sent to her by confused fans seeking an autograph.

She then turned to address somebody off camera before asking for “one more moment.”

“What do you want?” she playfully asked, turning the camera to the actress, who was sitting on a stool with her own set of photos and a marker.

“Who should I make it out to?” the actress asked, to which the singer replied, “Would you make them out to me?” as both giggled.

“#FINALLY,” the singer captioned the post.

Fans were delighted and took to the comments section to sound off.

“Was not expecting this at all ALL and I loved every moment!!” wrote a follower, while another gushed, “I love everything about this!!!”

“Would the real Michelle Williams please stand up!” quipped a third, with a fourth raving, “THIS WAS THE DEFINITION OF ICONIC!”

Their moment after the show wasn’t actually the pair’s first encounter.

Per a fan video shared to TikTok, the two Michelles marveled over their shared name onstage when the singer invited the actress to join her.

“OMG I just watched Michelle Williams meet Michelle Williams at ‘Death Becomes Her,” the TikTok user captioned the short video. Destiny’s Child’s “Say My Name” played over the clip.

The interaction between the actress and the singer wasn’t a complete surprise — the “Dawson’s Creek” alum, 44, teased the meetup during an appearance on “Watch What Happen Life With Andy Cohen” on April 3.

“Do you have a relationship or friendship with the other Michelle Williams, and have you seen her in ‘Death Becomes Her’ yet?” Cohen asked.

“I have my tickets for next week,” she responded.

As for the Emmy-winning musical artist, she’s playfully poked fun at the identical names before — and teased a meeting. In a March 10 Instagram post, she read a fan letter clearly meant for the “other” Michelle.

“Your work in movies like ‘Blue Valentine,’ ‘Manchester by the Sea’ or ‘The Greatest Showman’ has deeply moved me and many others, showcasing your exceptional talent,” read the letter in part.

Holding up the photo of the “Dying For Sex” actress that arrived with the note, the singer deadpanned, “Her hair is fabulous.”

“This is absolutely brilliant,” she went on. “Yes, Michelle knows what’s going on as well, and I cannot wait to see her. Hopefully sooner than later. It’s being worked out.”
