Kate Moss is planning a bachelorette party at the Ritz in Paris - because they will allow her to smoke indoors.

The 37-year-old supermodel - who became engaged to Jamie Hince earlier this month when he proposed to her while they were in bed together - wants to take 50 of her closest friends to the prestigious French hotel in June to celebrate her last days of being single with a 1930s Cabaret-themed party.

A source said: "Kate is going to make her hen do the biggest party yet. Girlfriends Sadie Frost, Beth Ditto, Alexa Chung, Alice Dellal and Janelle Monae should all be there.

"They'll allow her to smoke inside. Hotel bosses have also told her they will organise everything."

Kate and her celebrity pals will be joined at the party by burlesque dancers in cages and a grand piano, where she plans on singing for her guests.

The source added: "As Kate is the ultimate hedonist she wants this reflected in her shindig. The '30s Cabaret theme, with burlesque dancers in cages and a grand piano for Kate to serenade her guests while the champers flows, is her idea of the perfect party."

Kate - who has an eight-year-old daughter Lila Grace with ex-boyfriend Jefferson Hack - and Jamie had originally planned to tie the knot in Paris, but their plans were scuppered when it emerged that they were ineligible to marry in France.

According to reports, the couple would have had to spend at least 40 days living in the country before it would be allowed for them to marry there.
