The enigma with Jennifer Aniston is that people tend to either love her or think she’s an absolute wreck, and apparently I’m one of the few people that are in between. All that said, everyone has moments of irrationality - and Jen had a pretty public one the other night. While backstage at boyfriend John Mayer’s Hard Rock Calling gig in London’s Hyde Park, Aniston spied Kimberly Stewart hanging out. Kim’s the daughter of Rod Stewart and is generally known for… er… hanging out.

John clearly has a bit of history with the model as all hell broke loose when clingy Jen spotted 28-year-old Kim backstage while John was warming up. Ever the gent, John tried to defuse the situation by getting his security to boot out Kim. And as the bouncers chased after Kim, Jen, 39, eyeballed her rival to warn her off John.

According to the Mirror, Aniston ordered Kim banished from the backstage area – and Kim refused to listen. “Kim was pulled off the stage and escorted through the Hard Rock VIP tent with a face like thunder, shouting: ‘Why doesn’t he want me here? Is this because of her?’ “She totally embarrassed herself, but Jen looked relieved.”

Update:

I don’t think anyone came out of that situation looking good. Aniston looks jealous and crazy, Stewart looks like a pathetic moron for sticking around until she was forced about by security, and Mayer looks whipped. Although frankly, that’s not really the worst situation for him to be in, considering the way he seems to use and go through women.
