Stray Kids is headlining major music festivals in Europe in July -- I-Days in Milan and BST Hyde Park in London -- for the first time as a K-pop boy group.

Stray Kids is taking the stage at the Ippodromo Snai San Siro in Milan, Italy, on July 12 for I-Days.

They will then perform at Hyde Park in London on July 14 at BST Hyde Park.

I-Days is a music festival that began in 1999 and has since then boasted a star-studded lineup of performers including Green Day, Liam Gallagher, blink-182 and Justin Bieber.

Other headliners of this year's I-Days include Doja Cat, Lana Del Rey, Bring Me The Horizon and Sum 41.

BST Hyde Park, which was established in 2013, invited Blackpink last year as the first K-pop artists to headline the festival.

Other headliners at this year's BST Hyde Park include Andrea Bocelli and Robbie Williams.

Stray Kids has performed globally recently, including their performance at Le Gala des Pieces Jaunes, or The Yellow Pieces Gala, held in Paris on Jan. 26 -- a first for a K-pop boy group.

The Yellow Pieces Gala is a musical charity event established to raise funds for the Hospital Foundation, a charity institution chaired by France’s first lady, Brigitte Macron.

With their latest release, “Rock-Star,” Stray Kids recently topped the Billboard 200 chart for four consecutive weeks. “Lalalala,” the lead track of their album “Rock Star,” also earned the group its first career entry on Billboard’s Hot 100.

Stray Kids also made their career debut on French music industry association SNEP’s 2023 Top 200 Albums chart, landing at No. 52 with third LP “Five-Star,” a record-breaking feat for a K-pop artist.
