So is THIS Paris Hilton's BFF? Miss Hilton vamps it up as she continues search for best pal

Since her days as a co-star on The Simple Life with Nicole Ritche it was clear having a friend by her side was a vital fashion accessory for Paris Hilton.

And last night was no exception as the heiress turned up to a party in London with a fellow blonde partygoer.

It is thought that her guest was one of the contestants from her new TV show called Paris Hilton's My New BFF (which stands for best friend forever).

The pair partied away at the Matter club in the 02 Arena in Greenwich last night at an event to mark fashion brand Diesel's 30th anniversary.

The 27-year-old is currently in Britain filming for the new reality TV show which is coming soon to ITV2.

It will see her pick a new friend that she can hang out with when she comes to London who will be able to keep up with her fast-paced party lifestyle.
