Did you know that Paramore vocalist Hayley Williams was technically part of the Super Bowl Halftime Show over the weekend? This year’s Halftime Show featured rapper Kendrick Lamar as its performer, but Williams managed to sneak her way into the set through her vegan hair dye company Good Dye Young.

Kendrick Lamar hid a bunch of Easter eggs in his historic Super Bowl LIX halftime show. But there's one little nod you may have missed, but Paramore‘s Hayley Williams sure didn't. The rocker slipped into the comments on the Instagram feed of Good Dye Young earlier this week to jump for joy after see that Lamar and SZA's backup dancers had used the hair color brand she co-founded with stylist and makeup artist Brian O'Connor.

“Peekaboo,” a post on Good Dye Young’s Instagram account reads, “GDY Spotted on the Super Bowl Halftime Stage @kendricklamar & @sza Dancers’ showed up and showed outtt with Good Dye Young custom split dye by @luckylettty.” In the replies, Williams wrote, “Screaming at my TV!”
