Bride Expects Stripper but Gets Private Dance from Maid of Honor Dressed as Justin Bieber: See the Video (Exclusive)

A bride-to-be expected a stripper, but never imagined who was actually in front of her when her blindfold came off.

In April in Portugal, Megan Parry had a hen do, which is a pre-wedding celebration similar to a bachelorette party and is especially popular in the United Kingdom and Australia. When the soon-to-be bride was blindfolded and sat down on a chair in a dark room, "she thought there was going to be a Portuguese stripper." But her maid of honor, Ellie Millar , had other plans.

Having been friends with Parry since they were 16 years old, Millar knows her love for Justin Bieber runs deep.

"I knew she was obsessed with JB since the day I met her," Millar tells PEOPLE. "She's 100% still a JB fan."

Months before the party, Millar decided she would surprise her best friend with a performance from her childhood crush. Unfortunately, Millar doesn't have any personal connections to the pop star, so she went with the next best thing — dressing up as Bieber herself.

"[I] knew Justin needed to make an appearance [at] the hen do," Millar says.

Footage of Millar's performance went viral on TikTok , with the video gaining 2.4 million views and nearly 400,000 likes since being posted last week. "POV: it's your best friend's hen do and her first love was JB," Millar wrote in an onscreen text overlay, adding in the caption, "As maid of honour…I understand the assignment."

In the video, "Pony" by Ginuwine plays. The signature Magic Mike song convinced Parry that a stripper was coming, but once her blindfold was removed her jaw dropped in shock.

Suddenly, the music switched to Bieber's "Love Me." Parry's chair was faced toward the backyard. The screen door's motorized blinds slowly and dramatically lifted to reveal Millar, who served 2010s realness in head-to-toe teen Bieber style.

She wore his high-top kicks, white skinny jeans and beloved purple hoodie — a throwback to Bieber's concert outfit at Madison Square Garden in New York City on Aug. 31, 2010. The look — all from Shein — was completed with a headset microphone, brunette wig with side-swept bangs and purple baseball cap.  

"Everyone knew Justin was coming, but they didn't expect the full transformation," Millar tells PEOPLE. "I was nervous, but the second I saw Megan's face and heard everyone screaming… I came alive and Justin took over."

The 11 women went wild during the performance. They cheered, danced and sang along to Millar's rendition of Bieber's hit songs, including "Love Me" and "One Less Lonely Girl."

Millar had been practicing "for a few weeks" leading up to the celebration, and was happy that her hard work paid off. Parry couldn't get enough of the nostalgic private dance.

"She absolutely loved it and wants to go back in time and do it all again," Millar says.
