Rita Ora's 'My Little Pony' Hair Is A Must-See On Our Beauty List

Celebs color their hair all shades of the rainbow (ahem, Nicole Richie), but we thought our eyes were playing tricks on us when we saw Rita Ora's new colorful hairdo.

The 23-year-old British singer made an appearance at Michalsky Style Night in Berlin sporting a purple, teal and blonde dip-dyed ponytail that reminded us of "My Little Pony." The colorful tresses cascaded beautifully against her shoulder and added an unexpected pop to her all-black outfit.

Check out Ora's '80s-tastic hair below and see which other stars made this week's best and worst beauty list.

BEST: Rita Ora

Isn't this multicolored hairstyle rad? It almost deflects attention away from Ora's gelled sideburns. But with her neutral makeup, we give it a thumbs up.

BEST: Debra Messing

"The Mysteries of Laura" star's red hair looks really ravishing. Styled in big barrel curls, Messing's hair frames her face perfectly and accentuates her peachy makeup and navy eyeliner.

BEST: Jessica Chastain

Chastain is a vision of summer with her full, copper bangs, metallic gold eyeshadow and coral lipstick. The twisted updo helps to showcase those gorgeous chandelier earrings.

BEST: America Ferrera

We're getting pinup girl vibes from Ferrera with her glossy, side-swept waves, flirty eyelashes and red lips. Dewy skin helps to give this look a modern touch.

WORST: Kate Hudson

We're huge fans of '90s-inspired dark lipstick. However, this burgundy shade looks garish against Hudson's super tanned skin.

WORST: Rose McGowan

McGowan barely looks recognizable with her jet black locks all pulled back. We wished she would've spent a bit more time carefully choosing the best wine lip color for her porcelain complexion and filling in her brows so that they don't appear noticeably different.

WORST: Karina Smirnoff

The "Dancing With The Stars" professional has a lot going on with her over-plucked eyebrows, white eyeliner and melon red lipstick, which doesn't flatter her bronzed skin.

WORST: Alexia Dox

This is a messy fishtail braid to the extreme! While her makeup isn't entirely terrible, we just can't stop staring at all the flyaways.
