Maisie Williams Is 'Officially A Mermaid'; Debuts Sea Blue Hair!

Maisie Williams shows off even lighter blue hair as she arrives at the women’s final of the Wimbledon Tennis Championships on Saturday (July 9) in London, England.

The 19-year-old Game of Thrones actress debuted a dark blue hair color at the Tommy Hilfiger Serpentine Summer Party earlier in the week, but told fans she switched up the color a bit.

“Just got my hair re-dyed at @nevillesalon by the wonderful @senizalkan (pic later),” Maisie captioned on Instagram.
