Who would be so mean to our beloved Brit Brit?!

Britney Spears and son Jayden caught a departing flight out of LAX yesterday accompanied by her bodyguard, and apparently one traveler wasn't exactly the pop princess' biggest fan, because he yelled she was a "has been" as she made her way up the escalator!

Although the "Toxic" singer ignored the rude comments, a random fan jumped to her defense and shouted, "You're still relevant!"

The mother-of-two was most likely headed to Sin City to get back to work on her Planet Hollywood residency, but she recently enjoyed a much needed break to attend younger sister Jamie Lynn's wedding in Louisiana.

She will always be an icon, but can someone please hire this girl a stylist so she look as fabulous as she naturally is!
