Martine McCutcheon and Denise Van Outen looked incredible as they took to the judging panel for The Masked Singer live in Sheffield on Friday.
The actress, 45, looked slimmer than ever as she slipped into a gold disc minidress for the show alongside Denise, 47, who wowed in a fringed number.
Martine, who starred in the series under the guise of 'Swan', showed off her bronzed tan in the thigh-skimming dress having just jetted back from a family break abroad.
She styled her brown hair in soft waves and added a boost to her slender frame with nude stilettos.
Denise, meanwhile, amped up the glamour in her silver fringed mini dress which she teamed with silver heels.
The girls appeared in their element as they posed for a series of pictures backstage before taking to the stage and heading to the panel.
Martine told her fans on Instagram it was a case of "straight back to it" as she returned to her career commitments following her break away with husband Jack McManus and their son Rafferty, seven, last week.
"Back Home & straight back to it!! No rest for the wicked - But I loved getting dressed up and into Covent Garden for an event & then dinner with friends," the stylish star wrote in the caption on Friday.
"I think it’s definitely delaying the holiday blues a bit! It was such a fun night with lovely people and I remembered why I love my London and my work so much."
Fans rushed to compliment the beautiful actress, with one gushing: "You look so stunning martine! Your an inspiration and love your style."
Love Actually star Martine has lost a significant amount of weight in recent years, with her having ditched "crazy diets" in favour of doing what works best for her.
She has impressed fans with her toned figure in recent months and the actress has been an advocate for the Cambridge Diet Plan, which is said to have helped her lose around 21 inches from her body in recent years.
The Masked Singer show is touring around cities throughout the UK and sees some of the programme's favourite characters take to the stage, with different mystery celebrities being unmasked at the end of the show.
Joel Dommett and Aston Merrygold join the girls for the tour and it features some new costumes as well as characters from time gone by.
