Pregnant Amanda Holden stays in hospital for second night

Amanda Holden announced she was pregnant again last August

Pregnant Amanda Holden has spent a second night in hospital after pulling out of the latest round of auditions for Britain's Got Talent.

The actress, 40, has been under the observation of doctors since admitting herself to hospital on Monday.

Holden, who is more than eight months pregnant, was forced to pull out of the Blackpool auditions on Tuesday morning.

She had been due to join fellow judges Simon Cowell, Alesha Dixon and David Walliams on the panel.

Her spokeswoman could not confirm reports that she had gone into labour, only revealing that the TV star was in hospital "for observation".

The mother-of-one, who is married to Chris Hughes, showed off her baby bump when she attended Britain's Got Talent auditions in Manchester last week but was criticised for wearing high heels.

In response, the star tweeted: "I walk less than 25metres a day in heels whilst up the duff!#justsaying!"

Amanda Holden, who has never confirmed her due date, had a stillborn son last year but announced she was expecting again last August.
