The "Valentine's Day" co-stars were spotted at a game between the Columbus Blue Jackets and the Los Angeles Kings at the Staples Center.
According to People, earlier on Sunday, Swift picked up Lautner at LAX before heading over to the battle on the ice.
Later in the night the couple was reportedly spotted in a Beverly Hills hotel lobby together.
"Taylor Swift was all dolled up and looked super pretty," an eyewitness told the mag. "She didn't seem to mind the attention … Taylor Lautner, on the other hand, was hiding under a hoody."
Earlier this month, the "New Moon" star was seen in the front row of the country cutie's concert in Chicago, where he received a loving hug from the singer after her show.
When contacted by People, reps for both Swift and Lautner did not immediately return calls for comment.
