Her 25th birthday birthday is actually today.
But Scream Queens star Billie Lourd decided to celebrate her quarter century a day early with a fun rainbow and unicorn-themed pool party for family and friends in a garden in Beverly Hills.
Among the guests risking the blow-up rainbow water slide were Billie's Scream Queens pal Emma Roberts, 26, and Teen Wolf star Colton Haynes, 29.
