Megan Fox, a Taurus queen, rang in her 36th birthday over the weekend the way all rocker-chick royalty should — while wearing a crown and partying alongside P. Diddy in Las Vegas.

On Sunday, the actress celebrated another year of life with a star-studded birthday bash at Tao, Las Vegas. Megan sported a shimmery gold sequined strapless dress for the occasion, which she aptly accessorized with a blingy silver tiara. Skipping the jewelry, Megan let her outfit take center stage and finished the look with dramatic winged eyeliner and rosy cheeks while leaving her pin-straight hair and newly-debuted bangs to cascade down her back. Megan was joined by her fiancé, Machine Gun Kelly (Colson Baker), at the party, who wore a black turtleneck featuring a bedazzled collar.
