Hailee Steinfeld's Super Straight Hair, Plus More Celebrity Beauty Looks We Loved This Week

See ya later, beach waves. Hailee Steinfeld looked calm, cool and collected as she appeared at the Hollywood premiere for "Barely Lethal" sporting a super straight hairdo.

Steinfeld's sleek and shiny hair fell beautifully against her black mesh dress, with not a single strand of hair going awry. We're pretty sure her stylist prepped her locks with heat protectant before straightening and made sure to hold the flat iron correctly. But we would love to know how Steinfeld managed to keep it that way.

See Steinfeld's straight hairstyle below, and find out which other stars made our best beauty list this week.

Steinfeld's "Barely Lethal" co-star also wore pin-straight strands at the premiere, and we love how healthy her red hair looks. Black eyeliner, a bit of blush and nude lipstick round out Turner's red carpet beauty. You can't go wrong with the ghd Eclipse when straightening your hair at home.

Meanwhile at the Cannes Film Festival, Marion Cotillard took our breath away with her classic lob hairstyle and rosy makeup. L'Oreal Paris Colour Riche Lipstick in Saucy Mauve will give a you soft pinkish pout.

The supermodel looked picturesque at a "Fendi By Karl Lagerfeld" book launch during the Cannes Film Festival. Her loose and long locks flowed over her black bikini top and gave way to her beautiful complexion. We recommend trying Lancôme Miracle Cushion Liquid Foundation for fresh, dewy skin like Iman's.

What a stunner! The English fashion designer wore many lustworthy looks on the red carpet at Cannes, but this neutral smokey eye, berry lip and straight hair combo is our favorite. The Chocolate Eye Bare Palette by Too Faced Cosmetics is loaded with shadows that make recreating this makeup easy.
