Nicola Roberts spends ''a lot of time hanging out'' at Cheryl Tweedy and Kimberley Walsh's houses.

The trio's band Girls Aloud - also made up of Sarah Harding and Nadine Coyle - may have gone their separate ways four years ago following their brief reunion in 2012, and are now all busy with their own lives and families, but they make sure they are always in contact and regularly arrange to meet up.

Speaking to BANG Showbiz, the flame-haired beauty said: ''We spend a lot of time hanging out at each other's houses, and even when we're not together we're always speaking over text.''

And there's nothing the girls enjoy more than having a natter over a few beverages and a takeaway.

The 32-year-old singer said: ''I much prefer having drinks at home these days to going out, although we did plenty of partying in our Girls Aloud days!

''I love getting a good takeaway on a Saturday night, as I tend to cook and eat healthily during the week. My favourite takeaway cuisines are Thai or Indian.''

Meanwhile, there's been a lot of speculation over recent months about whether Girls Aloud will reunite next year for the 10-year anniversary of their number one single 'The Promise' and, while Nicola refused to divulge any plans, she has admitted that she'd ''never say never'' to a reunion.

She said when asked about the milestone: ''Who knows - never say never!''

But, in the meantime, aside from writing music and focusing on her solo career, Nicola has teamed up with the renowned Spanish sparkling wine brand, Freixenet for their new Prosecco.

She said: ''I chose to collaborate with Freixenet for the launch of its Prosecco as the brand ethos is something that really resonates with me. Prosecco is my favourite sparkling wine and it's fantastic to be able to enjoy this particularly premium bottle. Whether I've got the girls round for a Saturday night takeaway or I'm popping fizz at a party, I live for those special everyday moments.''
