Currently taking part in the BBC One gymnastics show, Lucy was "over the moon" to have survived another week in the competition after going head-to-head with Eastenders star John Partridge in the vault-off.
And to celebrate her nail-biting survival, Lucy joined her Tumble partner Billy Jacques and her best pal Lydia for a well-deserved night on the town.
Supporting Lucy, Lydia had watched her friend perform from the audience on Saturday night, later joining Lucy and Billy for some after-show celebrations.
Sharing a picture of them all, Lydia said: "Late night celebrations with my Tumble faves @lucymeck1 and Billy #Tumble #Coya."
Lucy gave herself the night off, looking gorgeous in a black leather, bandeau dress, to indulge in dinner, cocktails and a little Essex catch up.
Taking to Twitter while out with Lydia and friends, Lucy tweeted: "Dinner at @coyarestaurant with everyone! ... Me & @BillyJacques can't stop smiling. So happy!!"
And still feeling just as chuffed yesterday, Lucy tweeted for a second time. She said: "I'm over the moon I'm still in Tumble! I really wasn't ready to leave the competition, Thanks for all your support!."
On Saturday (30 August), Lucy took to the floor to perform her rhythmic, ribbon routine, but her performance scored the second lowest total of the night.
Despite her nerves, the former TOWIE star was saved by the Tumble judges after her vault and will go through to perform next week in the show's semi-finals.
Keen to do well, Lucy has been hard at training since and prior to her Tumble debut. Speaking of her new intense training regime, Lucy told Reveal it has given her a bum worthy of Kim Kardashian's!
She said: "It's completely changed my body shape and I love it. It's the only thing that has given me a bum! I'd tried everything, but it's the only thing that has made my bum go, "Oh hey!"
Well if that isn't reason to brush up on your gym skills, what is?!
Tumble continues this Saturday (6 September) on BBC One.
