The judge (49) donned a low-cut blue gown in the latest semi-final when she appeared alongside Ashley Banjo, Alesha Dixon and David Walliams.
Some thought she was showing a little too much for a family show.
The star has previously been the subject of complaints to Ofcom because of her revealing outfits.
On Saturday night, one viewer wrote on Twitter: “Can Amanda Holden please wear some more appropriate clothing for BGT.
“It is a family show and week after week the outfits (and they are stunning) just show more and more! It’s not appropriate especially as its our favourite show!”

Another added: “Did my eyes deceive me or was Amanda Holden flashing?”
Some were all in favour of the outfit, writing that the judge looked “utterly stunning”.
Last year, Holden told the Mail On Sunday’s You magazine: “I love it that people are still talking about my tired old breasts and I’m nearly 50!”
