Susanna, 49, looked gorgeous as she sat with her friend Judge Rinder to look at the latest TV shows, sending fans wild.
Whilst most of the celebrities don comfy clothes to watch the TV, Susanna looked as glamorous as ever in the animal print shirt dress.
Susanna flashed her legs as the skirt of the dress rode up her thighs, leaving viewers very hot under the collar as they rushed to compliment her.
One fan simply called Susanna “absolutely stunning”, as she giggled with her pal while watching shows such as Planet Earth II, Breaking Dad and the classic ‘Sharongate’ episode from EastEnders.
Another added: “How does anyone look that gorgeous watching telly? This is not normal, right?”
A third complimented the pair, writing: “Two of the smartest & nicest on tv… great pairing.”
Susanna was even forced to shut down her GMB co-star Piers over her outfit, as a promo clip of her appearance was shown on Wednesday.
Piers cheekily said: “I couldn’t get past her legs… the leopard skin leotard and these bare legs…”
Susanna hit back at the comment, putting Piers in his place by saying sarcastically: “It’s amazing isn’t it… I’ve got legs.”
She also admitted she was worried about appearing on the show, as she said: “You see, the benefit of doing a live programme is you’re always in control of what you say and what goes out.
“When you do a recorded programme, it’s in the hands of the editors.”
Piers chipped in, saying: “And as our friend Eamonn [Holmes] found out, the editing can be a bit savage, the editing process as they apologised to him.”
Eamonn said he was “hurt beyond belief” that his emotional discussion about his dad’s death was replaced with “a funny story” on Celebrity Gogglebox.
Good Morning Britain airs weekdays at 6am on ITV.
