Sarah Harding's two-day engagement celebration

Sarah Harding's engagement celebrations lasted over two days.

The 29-year-old singer and her fiance, DJ Tom Crane, celebrated in style with a host of celebrity friends at members-only club The Brompton in London on Monday (07.03.11).

She had such a fun night she didn't want it to end, and was still celebrating and singing in her room at the Kensington Hotel, which she didn't leave until 4pm the next day.

One reveller said: "Most people who attended were clever enough to book the whole week off. Sarah knows how to throw a good knees-up so everyone prepared for a wild night.

"We were still up at 2pm the day after singing karaoke in her hotel room."

The newly brunette beauty - who wore a black, floor-length dress - even teased guests who dared to leave earlier.

A source told the Daily Star newspaper: "A few friends left at 6am and Sarah phoned them up saying, 'Why did you bail? You lightweight.' "

They added: "Tom and Sarah looked so in love all night, dancing together to cheesy 80s songs.

"They drafted in crates of champagne and Jason Statham bought everyone a round of drinks."

Other celebrities who partied with her included Jason's model girlfriend Rosie Huntington-Whiteley and Sarah's Girls Aloud bandmates Kimberley Walsh and Nicola Roberts - but Cheryl Cole and Nadine Coyle did not attend.

However, Nadine took to her twitter account to wish her pal a great evening, writing: "I hope my lovely Sarah H has a great party tonight. Shame I can't be there due to commitments in US. We will have to have another one. Xx (sic)"
