Spencer, who plays the main character in the video, said: "The character is a guy who has just split up with his girlfriend. It's about one guy going through a pretty tough time in his life - asking loads of questions, being at war with himself."
Grimshaw continued: "It's a situation most of us have been through - splitting up with someone and getting angry.
"This video follows Spencer through his downward spiral and then it takes us back to see why he's made all these mistakes."
'Is This Love' - out June 3 - marks the first single from the star's debut album Misty Eye, which follows on August 13.
The singer first found fame as an X Factor contestant in the seventh series of the talent competition.
