Bruno Mars is postponing his 24K Magical Tour date in Denver slated for October 30 due to an illness, according to a record label spokesperson.

Mars, one of the most popular pop stars out in 2017, just released his third studio album, 24K Magic in November of last year. The world tour for the album kicked off back on March 28.

When the tour's finally over in July of next year, Mars will have played 46 shows in Europe, 75 shows in North America, 10 in Latin America, 18 in Oceania and 14 in Asia - 163 in all.

Mars announced on Twitter that he had a severe sinus infection and couldn't perform. He wrote that he had it in Dallas (his previous tour date) and was able to "power through," but that just made it worse.

He apologized to his fans in Denver. "I hate cancelling shows more than anything," he wrote. "I hope you can forgive me and trust that we will do everything we can to reschedule and make it up to you."

He was set to perform at the Pepsi Center.

The makeup date for the concert has not been released, but a spokesperson says a new one will be announced as soon as possible.

Below is the performance of his smash hit, "That's What I Like" during the 59th Grammy Awards in February of this year:
