The former XFactor star was beaming with happiness and visibly excited about the triumphant event as she stopped to pose for a number of beaming snaps with REHAB co-founders Anastasia Muca and Vicky Ellis.

For the occasion, Stacey wore an effortlessly stylish outfit, consisting of a white T-shirt with matching bomber jacket and oversized gray pants.

Wearing a pair of comfortable white sneakers, she sat solo in front of the beautiful stands a few times, showing off her perfect blow-dry hairstyle.

Stacey was left speechless on Wednesday night when she won the first award of the evening at the National Television Awards.

The presenter provided the first surprise early in the ceremony when Sort Your Life Out beat favourite Jeremy Clarkson to win the Factual Entertainment award.

The star looked visibly shocked when the name of her show was announced, before giving her 16-year-old son Zach a big hug and jumping up and down happily.

The star was supported by her Zach and sister Jemma as she took to the stage, after beating favourites including Gogglebox and Clarkson’s Farm.

Struggling to contain her excitement, Stacey enthused: ‘It’s the hardest show ever to make and they work so, so hard. My wonderful co-presenters.

“I’m so grateful to be doing a show like this, I want to thank the families who let us into their homes. If it wasn’t for the families who opened their hearts to us, there wouldn’t be Sort Your Life Out.”

Stacey concluded her speech by thanking her husband Joe Swash, who was unable to attend the awards ceremony, and her five children Leighton, Rex, Rose and Belle.

The star opted for a striking red dress for the prestigious evening, as she posed for snaps on the red carpet with Zach.

She paired the red silk corset-style dress with long black gloves and black heels, while her golden locks fell in voluminous waves over her shoulders.

Meanwhile, Zach looked stylish as he wore a simple black suit and vest.

Her sister Jemma also shone in a black, glittering dress with a feather trim.
