GALLAGHER VS. GALLAGHER. This one has presumably been going on since long before any of us ever heard of Oasis, and it came to a head when Noel stormed out on his little brother and his band in 2009. But as both bros embark on their post-Oasis careers, the eyebrow-fur continues to fly, and both Gallaghers are absolutely looking back in anger. (See what I did there?) This year, both Gallaghers filed legal action against each other, mostly as a way to call each other assholes in the most public way possible. Because when Twitter turns out to be too cerebral, there's always the legal system.
