Lea Michele attended Elle magazine's "Women in Hollywood" celebration on Monday night and made her first red carpet appearance since the death of her boyfriend, Cory Monteith, on July 13.

The 27-year-old wore a cut-out, strapless dress designed by Calvin Klein. She added a pair of strappy sandals with her hair pulled back for the Oct. 21 event, which was held at the Four Seasons Hotel in Beverly Hills.

The Glee star was spotted wearing a diamond ring on her finger as she walked through LAX on Sunday after spending the weekend with a few friends in San Francisco. E! News reported that, despite speculation, it was not an engagement ring from Monteith. She shared a picture of her trip in which she spent some time with friends Jonathan Groff and Skylar Astin.

"Back from an amazing weekend in SF with these boys!" she wrote. "So grateful for such amazing friends." 

Her Fox show paid tribute to Monteith and his character Finn in the Oct. 10 episode titled The Quarterback, featuring the students, faculty and alumni of McKinley High gathering together to mourn the loss of the show's star athlete and celebrate his life. Finn's longtime lover Rachel (Michele) returned in the episode's final act to deliver a heartfelt performance of Make You Feel My Love by Bob Dylan dedicated to the quarterback. 

Rachel explained that it was the song that she and Finn first sang in the car together.
