Jade Goody is set to marry her boyfriend Jack Tweed in a star-studded fairytale wedding on Sunday – despite last minute concerns for her health.

The cancer-stricken former Big Brother star was said to be “feeling unwell” on Saturday night following final preparations for her big day – although her spokesman Max Clifford said she hoped to be better by Sunday morning.

“Hopefully she’ll be OK in the morning. She’s possibly done too much today,” he said. “She wasn’t very well. I’m sure she’ll be fine in the morning after a decent night’s sleep.”

He added that he feared in advance that Jade might have a busy day as she prepared for the wedding, which till take place at Down Hall county manor in Essex.

“Knowing Jade, it was always going to be, but I always hoped it wouldn’t be,” he said. “Jade is Jade. It’s good that she’s busy. It gives her something to concentrate on.”

On Saturday Jade joked with photographers outside her Essex home as she emerged with her four bridesmaids, all of whom were wearing fake bald heads and matching trackuits.

The five of them travelled to London for teeth whitening treatment at an exclusive clinic before returning home for a wedding rehearsal.

However Jade was reportedly so tired that she had to hold on to Jack for support as they practised their vows – which poignantly left out the phrase ’till death do us part’.

An emergency medical team will be on standby throughout the wedding, while the 27-year-old’s hospital bed has also been taken to the venue, and her wedding dress modified to include a pouch for a moprhine drip.

But Jade kept smiling despite feeling unwell. “This is going to be the happiest day of my life,” she said. “I can’t believe I’m going to be a wife. It’s scary.”

Jack popped the question at Jade’s hospital bedside after she learned from doctors that her cervical cancer was terminal.
