UPDATE, 5/30: TMZ is reporting that the "sentimental" items allegedly stolen from her bag include a pair of sunglasses given to her by her late father, Robert Kardashian.
Of the allegations, the Telegraph reports, British Airways has responded:
“We are continuing to investigate this matter. Our customer travelled from Nice to Heathrow Terminal 5 to Los Angeles. Terminal 5 has some of the most sophisticated automated baggage systems in the world, which are able to monitor bags every minute of their time in the terminal. At this stage, we have discovered no evidence to suggest that the bag in question was interfered with at Heathrow. Our investigation is also seeking to establish details of the bag's passage through Nice and Los Angeles airports.”
PREVIOUSLY: Kim Kardashian took British Airways to task via Twitter, naturally, for "stealing" from her luggage on her way back from Europe (she was recently at the Cannes Film Festival).
In her somewhat scathing Tweets, Kardashian accuses the airline of taking "sentimental" and "not replaceable" items from her luggage, before adding "Shame on you."
No word on what Kardashian claims the airline took from her, but we're betting it's something shiny and new from Kanye.
Kardashian joins a list of celebrities who have Tweeted their displeasure with airlines. Last year, Lily Allen angrily Tweeted to Ryan Air for charging her to print her boarding pass, while, more famously, Alec Baldwin set off a firestorm for Tweeting angry words about American Airlines after the airline kicked him off a New York-bound plane for playing "Words with Friends."
