The 45-year-old musician says he loves the "Shape of You" singer's approach to music, reported FemaleFirst.
"I've been rubbing elbows at certain events with Ed Sheeran and we haven't had the opportunity to perform as a duet together but he has a beautiful style and approach and I like what he does and the way he can take a massive environment and make it small," says Porter.
The "Hey Laura" singer says he was impressed with Sheeran when he saw him perform at Wembley Stadium.
"I've seen him at Wembley, I saw him take that space and turn it into a tiny club and that is what you try to do wherever you are as an artist, try to create intimacy.
