Frankie is the newest mum of the clan but she tore herself away from son Parker before heading off to meet Rochelle, Una, Vanessa White and Mollie King in London.
The girl band were all dressed to impressed for their meal at trendy Japanese restaurant Nobu and it appears they used the dinner to exhange Christmas presents with one another.
When leaving the eatery, each of the girls were clutching bags stuffed with gifts as they headed to their waiting cars.
Frankie kept off the December chill with a long tailored black coat, which she teamed with a grey and black leopard print shift scarf.
The mum-of-one, who gave birth to Parker in October, was toting a bright orange designer handbag and flashed her sparking engagement ring.
Mollie, meanwhile, opted for an all-black ensemble and kept the rain off her pencil skirt dress with a funky leather jacket.
Rochelle - who is mum to daughter Alaia-Mai - also wrapped up in a black coat to protect herself from the downpour, while Una opted for a faux-fur trimmed leather number over her navy skater dress.
Adding a festive splash, Una, who has a daughter called Aoife, coordinated her frock with a bright red pair of pointed heels and a matching thin leather belt.
Vanessa, meanwhile, bravely dashed through the rain without a jacket, showing off her dark green leather skirt and pretty black knit with floral embellishments.
It appears the girls, who were joined by members of their record label, had a great night together and Una shared a snap of them all sat around the table in Nobu.
The gang are all grinning at the camera in the photo, which Una posted to Instagram.
