“When your sister hears ‘There Was This Girl’ and decides she IS the girl.”

Riley Green got an unexpected surprise during a recent show when a very enthusiastic fan attempted to crash his performance. That fan happened to be singer-songwriter Annie Bosko’s sister, Katie Boskovich, and according to Bosko, the appearance was completely unplanned.

While so many fans would love the opportunity to share the stage with Green, not many get the chance to make that happen. Unfortunately, the same was true even for Katie over the weekend, although she made a good attempt at turning this dream into a reality.

Bosko shared a video of the moment her sister confidently danced her way onto the stage in her long dress, cowboy boots and cowboy hat.

“When your sister hears ‘There Was This Girl’ and decides she IS the girl,” she wrote, making light of the situation.

Before Katie could get too close, security quickly stepped in and ushered her off to the other side of the stage. She continued to smile and sway along to the performance, while clearly trying to convince Green’s crew member to let her have her moment. She tossed one last wave in Riley’s direction before making her exit. The country superstar never acknowledged her unexpected presence on stage and has yet to comment on the situation.

Bosko joked that while she knew her sister “wanted to ‘support my career,’” she never expected that support to come from the stage alongside the headliner. The “California Cowgirl” singer also stressed that Riley Green never asked her to join him during the performance. It was entirely Katie’s idea, fueled by a little liquid courage.

She added, “FYI @rileyduckman didn’t invite her up — tequila did… and there was definitely more than one in her hand. God help me. Apologies team Riley. 🙏🫣”

The comment section of the post was filled with laughter as fans reacted to the unexpected cameo, calling the whole situation “hilarious.”

Bosko’s sister also made sure to jump in to share her side of the story. She joked, “I was trying to support his career!!!! 😂 also he had no backup dancers and you know how much I love being a backup dancer @anniebosko Can I be your backup dancer????”

Fellow musicians joined in on the fun as well. Natalie Stovall wrote, “OMG I’m dying,” while country musician Kyler Steven Fisher added a simple, “haha,” showing that even the professionals found the stunt entertaining.

This unforgettable encounter took place in the midst of the “Worst Way” singer’s 2025 tour which is set to wrap up with back-to-back nights at Resorts World Las Vegas on December 12 and 13.

Green will kick off 2026 with shows in Australia before returning to the U.S. to launch his biggest headlining tour yet.
