Brooke Mueller has a brand new boyfriend -- thanks to ex, Charlie Sheen.
She's dating country singer Jaron Lowenstein. They met last year at a party while Brooke was in the process of reconciling with Sheen.
Brooke and Jaron kept in touch over the next year, but a couple of months ago they decided to take their friendship to the next level and officially started dating.
