Paris Hilton just arrived in the British capital but she's already gone shopping! However, the socialite attempted to disguise herself during the shopping spree in London.

In an attempt to go unnoticed, the 34-year old hotel heiress sported a black wig, with a bob haircut and bangs and wore dark over-sized sunglasses as she hit the flagship store of Topshop in London. Even in disguise. Paris Hilton seemed pretty keen to pick up a bargain at the very fashionable clothing store, where she posed with several Topshop paper bags with her complete disguise.

The American socialite in disguise then later shared the snap on her Instagram account and captioned it, "So much fun" followed by the hashtag #UndercoverShopping. Paris Hilton tagged Topshop's IG account and even gushed about it.

"Always find the cutest clothes and accessories there! Loves it #ParisinLondon," she said.

Paris Hilton disguised herself well and looked extremely unrecognizable wearing a loose dark blue sweater, which featured a huge bow on the front and skinny jeans.  She also announced on her social media sites that she will be having a meet and greet in Liverpool the next day for the launch of her new fragrance.

Earlier that day, the gorgeous blonde revealed just how much luggage she needs to stay in Europe for a week or two. When Paris Hilton arrived at Heathrow airport, an airport employee was spotted pulling a trolley full of her bags.

Even when dressed down for the 10-hour flight, Paris Hilton still made a statement with her bright blue and red leather jacket which she paired with skinny jeans and black boots.

Paris Hilton gamely posed for the cameras as she arrived in London and looked extremely pretty with no makeup on and her hair in pigtails.

The reality star is currently in London to celebrate her new fragrance, with several scheduled appearances and signings all over the country. After shopping in disguise, Paris Hilton will join a European press tour to promote her new single called "High Off My Love" to be released on May 15 and will be showing off her DJ skills at Cannes Film Festival on Friday.
