Kardashian threw a bash for her new beau James Harden's 26th birthday on 25 August (15) but the event sparked a wave of complaints over a 15-minute fireworks extravaganza.

Now 12 local residents in Marina del Rey are to file a group action against Khloe and her mother Kris Jenner for emotional distress, according to TMZ.com.

They are reportedly demanding $7,500 (£4,687) each in damages.
