Gemma Collins looks slimmer than ever as debut single Baby It’s Cold Outside rockets into top 10 on first day

GEMMA Collins looks slimmer than ever in her silver sparkly dress as her debut single Baby It’s Cold Outside rockets into the top 10 on the day of its release.

The Only Way Is Essex star, 39, stunned in her dress as she posed on Instagram.

Showing off her incredible three-stone weight loss, Gemma stood in a wooden doorway while showcasing the sparkly silver dress.

She let her blonde hair fall by her shoulders as she looked at the camera with a face of flawless makeup.

Her fun snap comes as her hit number seven in the iTunes singles chart on the first day of its release.

All proceeds from the single goes to charity Rethink Mental Illness, which focuses on helping those affected by mental illness.

The single, released today, was a collaboration between her and ex Celebrity Big Brother co-star Darren Day, through indie label Rebel Records.

Last week the reality star dropped a teaser for her new tune on Instagram.

She shared a snippet of the two in the recording booth singing their own rendition of the Christmas classic, Baby, It’s Cold Outside.

, Gemma is stood in front of a microphone donned in a Christmas jumper as she introduces the song.

“To the nation, it is the GC and Dazzle,” she yells.

“He’s not claustrophobic anymore, he’s singing a song to cheer everyone up from what a terrible year this has been.

“Take it away, Dazzle!”

She told her two million followers: “I am SO EXCITED to let you know that my Christmas song is now on PRE – ORDER!”

The GC added: “I wanted to do something fun and fabulous for you all for charity as it’s been a tough year for all, I hope this spreads some cheer and warmth in your hearts. Head over to my story to pre order!!!!!”

Hopefully Gemma’s debut single will be a huge hit and bag the number one spot.

Singer Robbie Williams have backed the star for the Christmas number one after being left “stunned” by her incredible vocals.
