He told DJ Ryan Seacrest: "You know we haven't even spoken about it.
He appeared to be a little peeved about seeing his ex Taylor and Tom Hiddleston kissing on a beach near her Rhode Island home earlier this week but he claims he isn't too upset.
In a video published on TMZ, a pap asked for his thoughts on Taylor and Tom and he said: "It's all good, she's doing her thing, she's doing her thing, dude."It has been claimed Calvin, 32, feels "betrayed" over Taylor's new romance.
A source said: "He thought they were in a committed relationship and now he's p***ed and feels betrayed by her."What's more, when he was spotted out and about yesterday he was wearing a pair of Kanye West's Yeezy trainers - which just happened to be on the same day Taylor, Kanye and Kim Kardashian's feud flared up again.
Harris and Swift broke up in June and there has since been drama between the pair, most notably on Twitter when Calvin asked her to stop trying to "bury" him when it was revealed that she wrote his song .

Amazing lyric writer and she smashed it as usual (sic)."Tweet 2:wrote the song, sat down at a piano and did a demo into her i Phone. They both went into a studio and did a full demo with Taylor on vocals and Calvin doing the beat."The couple reportedly felt that their relationship would overshadow the song itself, so Calvin brought in Rihanna to record the vocals, and Taylor - who kept the publishing rights - was credited under the pseudonym Nils Sjoberg.
And much to Taylor's upset, on the day the song was released in April, Calvin said he "couldn't see" himself ever working with his then-girlfriend.
