From the Grammys and the BAFTAs to Mercedes Benz Fashion Week, stars were busy primping and polishing for some of the biggest annual events -- and that meant tons of sexy celeb style.

All eyes were on Sports Illustrated swimsuit model Samantha Hoopes at the Sports Illustrated Swimsuit Issue 2015 celebration -- and for good reason. The 24-year-old hottie sizzled in a super revealing white and silver gown.

Hot mom Gwen Stefani, 45, also looked totally killer in a masterful Atelier Versace jumpsuit on the Grammys red carpet. Bold eye makeup and creamy lips completed her stunning look.

Dakota Johnson has some steamy sex scenes in "Fifty Shades of Grey," and the 25-year-old breakout star totally smoldered at the premiere in a plunging white gown and dark lips.
