Sexy Stars: Courtney Stodden flashes her assets and Dakota Johnson stuns in slinky sequined gown

The temperature may be dropping but the sexiness this week is at an all time high!

With New York Fashion Week and the Grammys, there are way too many red carpets to hit -- and we're not complaining!

Dakota Johnson and her "Fifty Shades Darker" cast are currently overseas promoting the upcoming release of the new movie, and the leading lady has slayed every red carpet she's hit. Our favorite may have to be the slinky sequined dress she wore in Germany. Her costar, Rita Ora, also looked dazzling in a dark dress with some major under boob.

Meanwhile, celebs like Courtney Stodden and Noah Cyrus have dressed to impress at pre-Grammys parties. And 3,000 miles away in New York City, Katie Holmes blew us away with her deep red gown with intricate detailing.
