Few people could glance away from Tess' cleavage in one daring red dress earlier this series, and even the telly host herself confessed it was a mistake.
After watching herself back on the show, Tess admitted: "I went, 'Oh my god, why did nobody tell me about the boobs?'"
She revealed: "What happened was, the bra I had on didn't fit the dress so I wore one of those designs that has gel at the sides, which kind of pushes you up and, I guess, gives you an extra couple of cup sizes."
Tess, who has hosted the show since the first series, explained that even she found watching the show back distracting and would be making sure to cover up in future.
Unfortunate news for quite a few viewers, we expect!
She said: "I don't usually show a lot of cleavage, it's not in my comfort zone.
"That'll be the first and last time. The people at home don't want to see that, it's distracting."
