Holly Willoughby's famous boobs reportedly helped pull in almost nine million viewers on the 'The Voice' finale.
The Brit model showed off her twin assets in a revealing low-cut black lace dress, the Daily Star reported.
When the show commenced on Saturday night, the mum-of-two was soon the main topic of interest on Twitter, because of her daring outfit.
Even BBC's official account's message warned that one might need to lie down after seeing what Willoughby is wearing.
An awed fan tweeted that her boobs should be trending worldwide.
