The Scottish DJ was needled by host Howie Mandel while picking up the Future Icon award at Caesars Palace’s 50th anniversary gala.
Mandel, who is a Canadian comedian and judge on America’s Got Talent, introduced Harris with the line: “That’s a nice suit. Who’s your tailor?”
But Harris took the joke in his stride, replying: “You got that prepared. You had that one ready.”
Swift and Harris split up in June, the singer is reported to be currently dating actor Tom Hiddleston.
Last month, Harris posted a video of himself lip-syncing to Kanye West’s verse on Schoolboy Q’s ‘That Part’, prompting speculation that the two might be working together.
According to E! News, a source close to Harris said that the Scottish producer “wants to make some music with [West] down the road” and thinks “he is brilliant with music”.
Another source apparently told the network that the Kardashian family said they had “always thought” Harris was talented.
News of the potential collaboration comes after West’s wife Kim Kardashian West leaked videos of the rapper on the phone with Swift getting her approval for a line in his song ‘Famous’.
