Taylor Swift & Jake Gyllenhaal Break Up!

Taylor Swift and actor Jake Gyllenhaal have officially parted ways.

A source now tells People magazine, "They're over. It ended last month."

Cluing insiders into the breakup was the fact that Taylor and Jake spent both the Christmas and New Year's holiday apart - as well as their birthdays.

Another insider told Us magazine of the reason behind the split, saying, ""Jake reached out to her and started all of this, but now he’s not acting as interested. He said he wasn't feeling it anymore and was uncomfortable with all the attention they got."

The Us source added, "He also said he could feel the age difference. Taylor is really upset. We told her not to move so fast with this but she didn't listen."
