While Usher's performance at the Super Bowl Halftime Show was loaded with guest stars, one notable person who didn't perform was Justin Bieber.
Per Sara Nathan of Page Six, Bieber declined an invitation from his longtime friend and mentor because he "just wasn't feeling it."
Nathan noted there's "no bad blood" between Bieber and Usher. It was just a situation where Bieber "wasn't up for" doing it.
TMZ reported on Friday that Usher was talking directly to Bieber about potentially being part of the event. The two musicians have had a longstanding relationship that began when Usher started to mentor Bieber very early in his career.
