Calvin Harris only has eyes for Taylor Swift .
Ahead of his upcoming Fourth of July show in Las Vegas, the 31-year-old DJ jetted to Dublin, Ireland to support his girlfriend, who took the stage on Monday at the 3Arena as part of her 1989 World Tour.
Sneaky fans happened to snap photos of the Scottish producer standing near the sound deck, doting on his gorgeous gal as she belted out her most famous hits. Another fan also captured a video from the concert, which sees the 25-year-old superstar sweetly gesturing to her man while singing her tune “I Know Places.”
