Taylor Swift is no stranger to calling out her ex-boyfriends so it's no surprise that the "Red" artist threw some subtle yet major shade at her ex-boyfriends when she took the stage at the 2014 Teen Choice Awards on Sunday, August 10th at the Shrine Auditorium in Los Angeles, California.

According to Us Weekly, the "Sweeter Than Fiction" singer, 24, who was both an award winner and a presenter at the show snagged a surfboard for Choice Female Country Artist and introduced the category of Choice Actor in a Drama Movie.

During her presentation she used the airtime to diss the previous men in her life that didn't treat her ideally. Taylor Swift walked up to the microphone on stage and said, "Oh hey guys."

She continued, "You know we've had some amazing memories here together at the Teen Choice Awards. And so, I was excited when they asked me to come and present this award, because no one knows more about dramatic males than I do."

In the past the blonde beauty has dated Jake Gyllenhaal, John Mayer, Taylor Lautner, Joe Jonas and Conor Kennedy.

Swift's mention of the past "dramatic males" in her life caused the audience to erupt into laughter before she introduced the nominees for the category which included Ansel Elgort for "The Fault in Our Stars," Bradley Cooper for "American Hustle," Russell Crowe for "Noah," Jason Dohring for "Veronica Mars" and Jon Hamm for "Million Dollar Arm."

In the end, 20-year-old Elgort took home the award for playing Augustus Waters in the tragic cancer love story.

Meanwhile, Taylor Swift looked effortlessly chic in a two-piece crop top green outfit by Novis and bright yellow Charlotte Olympia shoes.

Swift was up against one of her most famous ex-boyfriends, Harry Styles for Choice Smile but lost the award to him. He also beat out her pals Selena Gomez, Demi Lovato and Austin Mahone
