The 2019 iHeartRadio Music Awards host started the show with a bold confession.
The "Buy U a Drank" singer hosted the awards show at Los Angeles' Microsoft Theater, and started things off by clearing the air with Taylor Swift, after being haunted by their not-so-smooth first introduction.
“Taylor, I never apologized to you. The first time we met -- you’re so much taller than me, that I thought you were standing on something," he began.
"Without looking down, I tried to stand on whatever I thought you were standin' on and -- bam! Headbutted you right in the boob," T-Pain cracked. "I'm so sorry. That was not my intention."
The camera panned over to Swift, whose laughter implied she accepted T-Pain's apology.
The Masked Singer winner told ET's Lauren Zima before the awards show that he planned to do his own thing on stage. "Within the legal rights," he joked. "Hopefully I got other stuff to do, so I don't have to worry about them hiring me next year, and I can kind of go crazy up there."
T-Pain does have a new album, 1UP, out now, as well as an upcoming tour. And he's still getting a lot of love from his time on The Masked Singer.
"I didn't think Lil Wayne would watch a show like that, but he was glued to it. He watched it every time it came on," he revealed. "So, appreciate it, Lil Wayne. Thank you, brother."
