British singer-songwriter Olivia Dean has added another major achievement to her growing career after performing before nearly 97,000 fans at Lollapalooza 2026, marking her first time headlining a music festival in the United States.

The 27-year-old artist shared the milestone on social media, describing the experience as emotional and unforgettable. She admitted feeling overwhelmed before taking the stage and thanked fans and her team for their continued support throughout her musical journey.

Dean delivered an energetic performance that received an enthusiastic response from the massive crowd, making her American festival debut one of the standout moments of this year’s event.

The latest success comes only days after Dean celebrated another landmark achievement in the United Kingdom. Her duet with British singer Sam Fender, “Rein Me In,” has officially become the longest-running number one single in UK chart history, setting a new national record.

During her performance at Lollapalooza, Dean took a moment to acknowledge the historic accomplishment and shared her excitement with the audience. She then welcomed Sam Fender to the stage, where the pair performed “Rein Me In” together for the first time in the United States.

The chart-topping track is a re-recorded duet from Fender’s third studio album, People Watching. Released in June 2025, the song climbed to the top of the UK Singles Chart in early 2026 before going on to achieve its record-breaking run.
