Both Miley Cyrus and her fiance Liam Hemsworth attended the 2013 Teen Choice Awards on Sunday, but the engaged couple was not photographed once together the entire evening.

The Hunger Games: Catching Fire star attended the event as a presenter, giving the award for Choice Movie Actress: Comedy to Pitch Perfect's Rebel Wilson at the Gibson Amphitheatre in Los Angeles, Calif. The 23-year-old Paranoia actor also presented the award for Choice Movie Actor: Comedy to Wilson's co-star, Skylar Astin.

Cyrus, 20, won the Candie's Choice Style award as well as Choice Summer Song for We Can't Stop and Choice Scene Stealer for her guest-starring role in Two and a Half Men.

As she went on stage to accept her award for We Can't Stop, the cameras panned out to her father Billy Ray Cyrus, whom she sat next to at the event instead of her fiance. Cyrus also brought along her younger sister Noah Cyrus and took with her on stage when she went to accept the award.

Upon accepting her style award, Miley told the audience what it takes to be a "trendsetter."

"You have to have an amazing group of people to follow your trends," she said. "I encourage you guys to always be different. Smilers, Dad, Mom, everybody - thank you!"

After her win she posed in the press pit for photographers, but Hemsworth was not beside her.

The last public appearance Miley and her fiance made together was at the Aug. 8 Los Angeles premiere of his film Paranoia. See photos here.
