Boston, Massachusetts - Rapper Post Malone returned to Boston to play a show he canceled last month, and sent fans off with a nice surprise as an apology.

Post hit the stage at TD Garden on Monday, playing the rescheduled date and letting fans know just how sorry he was he let them down the first time around.

"I'm so f***ing sorry, and I just wanted to say thank you for coming out tonight ladies and gentlemen," he reportedly said during the show. "It means the f***ing world to me."

To show his fans just how much he meant it, he told everyone to grab a free shirt on their way out.

The shirt features an exclusive design of the White Iverson singer in a Boston Celtics jersey with the TD Garden date on the back with "Love ya'll so much Boston," scrawled by Posty himself.

Malone suffered a brutal fall during his recent tour stop in St. Louis in September, which landed him in the hospital. Despite the serious injuries, he initially tried to gut it, but his condition worsened, and he was forced to cancel the Boston gig only a few hours before showtime.

"I woke up to a cracking sounds on the right side of my body," he explained in a Twitter post. He went on to say he was having difficulty breathing and was feeling a stabbing pain.

Post Malone went out of his way to make it up to his fans, and they seemed to love him so much more for it.
