Los Angeles, July 21: Singer Taylor Swift is reportedly dating actor Matthew Gray Gubler.
Gray Guble is known for playing criminal profiler Spencer Reid on TV show "Criminal Mind".
"Taylor is nuts about Matthew," showbizspy.com quoted a source as saying.
Gubler was a special guest at Taylor's bash in Rhode Island July 4, but she was apparently trying to keep the romance under wraps.
"She posted photographs from the party on her blog that showed her backup dancers, but Matthew's picture was conspicuously absent. It was as if Taylor was purposefully trying to keep his presence there on the downlow. Taylor's trying to keep the whole relationship with Matthew secret for now," the source added.
Some of the Swift's past love interests include singer Joe Jonas, actor Taylor Lautner and One Direction singer Harry Styles.
