Brighton-born TV star Holly Willoughby has announced she is pregnant with her third child.

The This Morning host, who is married to TV producer Dan Baldwin, posted the "surprise" news on her website.

Former Burgess Hill School for Girls pupil Willoughby, 33, posted a link to the announcement on her Twitter page, where she said: "I've got something to tell you..."

With reference to another ITV show she presents, the TV regular said: "Surprise Surprise (and it was a surprise!!) I'm really happy and excited to tell you that Dan and I are expecting baby number 3!!

"We feel blessed and very lucky to be giving Belle and Harry a little brother or sister later this year."

Last year Willoughby sparked controversy after some viewers complained about her ''unsuitable'' choice of low-cut dress in the final of The Voice, the BBC talent show she used to present.

She wore a racy black lace maxi-dress that attracted more than 100 complaints about the show, broadcast in the main before the watershed.

A BBC spokesman said at the time: ''We're sorry if some viewers found Holly's dress to be unsuitable.

''Holly enjoys fashion and we felt the dress she wore for the live final of The Voice UK was glamorous and wholly appropriate for the occasion.

''We don't believe it would have gone against audience expectations for a TV spectacle such as this.''

Communications watchdog Ofcom decided not to investigate the complaints.

Last summer Willoughby joined forces with her sister Kelly to write their first children's book, which follows twins Molly and Maria as they start their first term at drama school.
