'Mean Girls' actress Lindsay Lohan has ''offended'' an exclusive Los Angeles boutique after demanding they gave her $15,000 of free clothes.

Lindsay Lohan has 'offended' a designer boutique after demanding free clothes. The 'Mean Girls' actress has upset exclusive Los Angeles boutique Kitson - which stocks Lindsay's leggings line 6126 - after she reportedly demanded $15,000 in free merchandise from a shop assistant earlier this month. Store owners are upset by the 23-year-old's demands because she reportedly failed to fulfil her promotional duties after they splashed out a huge sum on stocking her leg-wear range. A spokesperson told Fox News: 'We're actually really offended. The tables have turned and now we're the customer. 'We spent $50,000 on her leggings line, but she hasn't come to the store in three years, and she didn't even do a personal appearance. ' Staff at the shop - which is on Robertson Boulevard - have now threatened to withdraw the collection from their store. The source added: 'She should have brought cookies for the staff to thank them for selling her leggings because she does nothing. We don't know if we'll continue to carry them.'
