Things got awkward fast at Caesars Palace's 50th anniversary gala in Las Vegas on Saturday, when comedian Howie Mandel surprised Calvin Harris with a joke about his ex, Taylor Swift.
Mandel presented Harris with the Future Icon Award on stage, when he couldn't resist a little ribbing.
"I like your suit, who's your tailor?" Mandel, 60, cracked. "See what I did?"
Harris laughed off the pun, but definitely looked more than a little embarrassed.
"Wow, you had that prepared. You got that one ready," he told the America's Got Talent judge.
Mandel hosted the night's festivities, which also featured a Tony Bennett performance, and a welcome from Jennifer Lopez, who's currently enjoying her own Vegas residency
. Harris maintains a residency
at Omnia nightclub inside Caesars Palace.
The Scottish DJ, 32, posted a pic with Bennett on Instagram, excited to spend time with the 90-year-old crooner.
"An honor to meet a living legend!!!" he wrote.
