Justin Bieber finally met his celebrity doppelgänger, Ruby Rose, while the two were at the Wynn Las Vegas during the Electric Daisy Carnival (EDC) this weekend.

The Australian actress and the "Baby" singer were introduced backstage during Avicii's show at Encore Beach Club, reports E!News. Rose took to Instagram Saturday, posting a picture of them together with the caption, “#twinning." Another Instagram photo shows Bieber taking a selfie while his friend, Christian Beadles, does the same. Rose captioned the picture, "Haha photos of photos of photos."

Rose, who plays "Stella Carin" on the television series "Orange Is the New Black" (OITNB), has been mistaken for Bieber on several occasions. In an interview with Vanity Fair published June 10, Rose revealed that she was followed by a group of girls while in walking Los Angeles last year, whispering, “Is it Justin? Is it him?” Her resemblance to the singer was even jokingly mentioned during an episode of "OITNB" where Alex (Laura Prepon) referred to Stella as "Justin Bieber."

The two stars began their friendship on social media last week, stated Entertainment Tonight, when Bieber shared a photo of Rose playing a piano filled with plates that had his face on them, to which she replied, "You're welcome to use it anytime." The two eventually met in Las Vegas, where Rose called Bieber her "brother," tweeting “So this happened.. @justinbieber haha my brother."

Justin Bieber was in Las Vegas over the weekend to perform during the EDC festival. The Canadian singer warmed up the crowd with a drum solo before Chris Brown’s performance at Drai’s BeachClub at The Cromwell. He also shared a snap of himself with DJ Kaskade on Twitter, writing “my brothaaa @kaskade”. But what truly made the weekend spectacular for Bieber fans was when the "Boyfriend" singer gave an impromptu rendition of his hit song "Where Are You Now."

Meanwhile, actress Ruby Rose made her US television debut on Netflix’s series "Orange is the New Black." The tattooed star is engaged to clothing designer Phoebe Dahl, granddaughter of Roald Dahl, the author of the children’s book "Willy Wonka & the Chocolate Factory."
