Post Malone and Justin Bieber have made their bromance very public on Instagram. Now that the Biebs will be walking down the aisle with Hailey Baldwin, Posty is doing what any good buddy would: offering his services for the big day. TMZ caught up with the "Psycho" rapper in West Hollywood Thursday afternoon (July 19) to see if he would perform on Justin and Hailey's wedding day. 

"Congrats. I would love to perform -- fuck yeah for free. I'll be the flower boy or is that the ring bearer? He's very happy and I love to see my boy happy," Post added while snapping a number of selfies with fans on the sidewalk. 

Baldwin's aunt Kim Basinger recently revealed that the bridal party has already been determined for Bieber and Baldwin's wedding, but didn't give any details about the groomsmen lineup. Bieber hasn't dropped any hints either, but recently shared a picture with Post captioned, "Your a beautiful person Posty! Truly an honor to know you my brother!"

Bieber aside, 2018 has been a huge year for Post Malone. After the successful release of his sophomore album back in April (April 27), Beerbongs & Bentleys, Malone notched a number of nominations at this year's upcoming MTV Video Music Awards, including artist of the year and song of the year.
