The reality TV star had been visiting the UK and Europe to promote her new fragrance 'True Reflection', and even put up an appearance at the Cannes Film Festival in France.
On reaching Los Angeles on board a British Airways aircraft, she took to twitter to complain that some of her belongings had disappeared from her luggage.
"Very disappointed in British Airways for opening my luggage and taking some special items of mine! Some things are sentimental and not replaceable," tweeted the 31-year-old.
Officials at the airline are baffled as to how on Terminal 5, fitted with some of the most sophisticated automated baggage systems in the world could allow such laxity in monitoring, reports Daily Star.
"At this stage, we have discovered no evidence to suggest that the bag in question was interfered with at Heathrow. Our investigation is seeking to establish details of the bag's passage through Nice and Los Angeles airports," said an official of the British airways.
