Taylor Swift received a big surprise while finishing up a show on Saturday (Feb. 1) at London's O2 Arena.

The singer was in London on the European leg of her Red Tour, and during the last song of one of five sold-out shows at the O2, a male fan rushed the stage, making it past security and all the way up to Swift at the top of the set before being escorted away.

The fan didn't seem to mean any harm and simply gave Swift a note, receiving a smile and a handshake from her in return. A Swift fan account on Twitter posted a photo of the incident:

Swift is performing at the O2 Arena in London again on Feb. 4, 10 and 11, as well as heading to Berlin's O2 World on Feb. 7.
