Taylor Swift did a lyric switch Sunday night during the 2013 Grammy Awards prompting some to believe that she was taking a shot at an ex who so happens to have a British accent.

While performing on stage Swift sang "We Are Never Ever Getting Back Togheter." But a few update lyrics had some believing that Swift may have been singing the song about a more recent ex, like Harry Style for example.

Dressed in an all white suit and dress coat, paired with a top hat and white boots - the Grammy nominated singer opened the stage with a white circus themed costume.

"So he calls me and goes, 'I still love you...,'" Swift began on stage, faking a British accent. "And I'm like, 'I'm sorry, I'm busy opening the Grammys."

The phony accent seemed to be a direct shot at ex, Harry Style, whom Styles separated with in January. The couple allegedly got in a fight while on vacation causing Swift to run home without speaking another word to Styles.

The split did not come as a surprise, according to sources, who stated that friends close to the couple were not taking the relationship "seriously."

Swift of course, has switched her lyrics up before while performing on stage. While performing at the Cannes the sang the "We Are Never Ever Getting Back Together" in French.

Before singing on stage, the singer walked the red carpet in a white gown decorated with diamonds. She wore a J Mendel dress with Jimmy Choo shoes, Lorraine Schwartz earrings, an Ofira ring, and a bracelet by Jaimin with Lorraine Schwartz. The singer tied her hair back in a braid and bun although she wore it down for her on stage performance.

"Oh my god, it's Grammy week, it's so hectic," she said to red carpet host, Ryan Seacrest. "I have a lot to plan for with the opening performance and I'm just really hoping all the pieces come together this week. Because this is when it really gets really crazy, but it's all very exciting too."
