People Editorial Guidelines Published on February 10, 2019 09:02 PM Share Tweet Pin Email No one has had a more exciting awards season than Lady Gaga. The superstar continued her red carpet reign on Sunday at the 2019 Grammy Awards, where she won three gramophone statues — one for best pop solo performance for her song “Joanne” and two for her chart-topping rock ballad Shallow from the critically acclaimed film A Star Is Born. And she went for full-on rock star glam in her disco ball-inspired Celine by Hedi Slimane gown. The sparkly design first hit the runway as a mini dress, but the singer made one small tweak for the red carpet: She elongated the hem transforming it into a long column gown with a sexy, thigh-high slit. She teamed the look with metallic Jimmy Choo platforms, loose textured waves and a sexy smoky eye. Gaga also piled on the sparkle via over 100 carats of Tiffany & Co. jewelry including a Tiffany Blue Book Collection necklace that took over one year to design and features 91 total carats of diamonds. She also added princess-cut Tiffany diamond earrings containing a total of 10 carats.
