Kim Kardashian is planning a "wedding slim down".

The 30-year-old socialite - who will marry basketball star Kris Humphries later this summer - revealed she will start using weight loss supplement QuickTrim again, on which she has previously lost 15lbs, in order to get in shape for her nuptials.

When one of Kim's twitter followers tweeted her yesterday (20.06.11) saying, "On my way to GNC to buy some quicktrim", Kim responded by writing, "Take some for me! I'm about to start again! Wedding slimdown (sic)"

Kim has also been beautifying herself ahead of the big day by using at home skin care and hair removal treatments from TRIA Beauty.

She tweeted: "I have been using the new @TRIABeauty Laser since they first sent it to me to try & now I'm fully ready for summer!"

Although Kim has not announced the date of her wedding, the reality TV star and her fiance - who proposed with a 20.5 carat Lorraine Schwartz diamond ring - are said to be eager to tie the knot as soon as possible.

A source said: "The wedding will happen within six to eight weeks.

"The wedding shower will take place about a month from now. They're doing things very, very quickly. It's being fast-tracked."
