Britney Spears just dropped her birthday outfit on Insta and it’s a total vibe shift! Instead of her usual bold looks, she went for a super cute off-shoulder polka-dot minidress with a black bow—think Minnie Mouse but make it pop star. She even said she’s obsessed with the new Minnie cartoon and feels like she’s five again. Honestly, loving this playful side of Brit! #Beauty #BritneySpears #BirthdayLook
