Starstruck viewers find themselves distracted by Sheridan Smith’s revealing outfit

STARSTRUCK viewers were left distracted by Sheridan Smith's VERY revealing outfit on tonight's show.

The 40-year-old actress showed off an impressive amount of cleavage in a plunging black dress.

Olly Murs welcomed the next four teams of superfans who went head-to-head as they transformed into their idol for a very special performance.

But ITV fans were left hot under the collar by Sheridan's eye-popping display in the figure-hugging number.

Wearing her blonde wavy tresses loose in a half updo, Sheridan stunned in the skintight outfit which drove fans wild.

At one point, the actress got up and had a boogie leaving little to the imagination as she bounced to the beat.

Viewers were unable to concentrate on the musical show, with one writing: "Omg Sheridan's good her boobs out again. #Starstruck"

"#Starstruck all hail The Rack of Sheridan Smith," a cheeky fan commented.

Another posted: "I hope you're all prepared for Sheridan to have her freshly buttered baps out again. #Startruck"

"I can't concentrate on tonight's episode, not as long as Sheridan is wearing that dress," a fourth joked.

On tonight's show, the panel was wowed by contestants who tried to impersonate their musical heroes - impersonated Whitney Houston, Gary Barlow, Harry Styles and Barbra Streisand.

This isn't the first time that Sheridan's outfit choice has stolen the show, she wowed in a low-cut pink frock last week.

The velour number featured a plunging neckline which showed off her cleavage and had fans very distracted.

"Jeez, I’ve never noticed how huge Sheridan Smiths knockers are!" one fan wrote on Twitter.

Another added: "Sheridan’s cleavage stealing the show tonight! If you’ve got it, flaunt it!!"

And a third wrote: "Sorry but I’m really trying not to be distracted by Sheridan’s cleavage but it’s proving absolutely impossible!"

Sheridan, who rose to fame in The Royale Family, said of taking part in the singing show: “Growing up, I always loved watching Saturday night TV with my family so I'm thrilled to be joining Starstruck. 

“Creating Cilla Black for TV, I know first-hand how much goes into becoming an iconic music star, so I can't wait to see what some of the contestants do with our modern music acts and true icons. 

“And with everything else that's going on at the moment, this is just the type of show we can all enjoy together!”
