The 50-year-old hunk, who is planning to tie the knot with
fiancee Angelina Jolie, is apparently hoping the band, which includes brothers Caleb, Jared, Nathan and cousin Matthew Followill, aren't on tour on the big day, reported Contactmusic.
The 'Sex On Fire' rockers have a few UK dates lined up for
the summer, including headlining Isle Of Wight festival in June.
"Brad ended up partying with Kings Of Leon last week. He spent most of the night talking to Caleb and he sounded them out about playing. It will happen if they can make the dates work," a source said.
"It's been a long time coming but finally it is going to happen," the source added.
Pitt partied with Kings of Leon following the band's Los Angeles gig last week.
