Taylor Swift and Tom Hiddleston's whirlwind romance is over.
ET can confirm Swift and Hiddleston broke up after three months together. "It was an amicable split," our source says.
However, according to a report, the 26-year-old singer was the one to come to the decision.
"She was the one to put the brakes on the relationship," a source tells Us Weekly. "Tom wanted the relationship to be more public than she was comfortable with."
"It was an intense start," an insider adds. "No one can keep that kind of momentum going."

Swift and Hiddleston, 35, were first romantically linked in June, when they were snapped kissing on a beach outside of her multi-million dollar home in Watch Hill, Rhode Island. The "Shake It Off" singer had split from her ex, DJ/producer Calvin Harris, earlier that month.
Following the pair's steamy beach pics, the two embarked on a whirlwind international romance, going on romantic dates in Italy, England, Nashville, and Australia, where Hiddleston's currently filming Thor: Ragnarok. Swift even met Hiddleston's mother, Diane, in June, when the two went to England to visit her.
And the couple certainly wasn't shy when it came to showing PDA. Hiddleston attended Swift's annual star-studded Fourth of July bash at her home in Rhode Island, donning an "I Heart T.S." top.
In July, Hiddleston confirmed his relationship with Swift.
"Well, um. How best to put this? That notion is -- look, the truth is that Taylor Swift and I are together and we're very happy," he told The Hollywood Reporter. "That's the truth."
