Frankie Sandford is missing alcohol.

The Saturdays star is expecting her first child with soccer player Wayne Bridge and has admitted that although she's not a ''massive drinker'' she is finding it difficult to abstain from drinking now she is pregnant.

Speaking to BANG Showbiz at the European premiere of 'The Hangover Part III' on Wednesday (22.05.13), she confessed: ''I've never been a massive drinker, but now I am not allowed I am like, 'Oh, I kind of want one.' ''

However, the 24-year-old beauty's drinking days could soon be behind her - if bandmate and fellow proud mum Una Healy is to be believed.

The flame haired 31-year-old - who has 14-month-old daughter Aoife Belle with rugby player Ben Foden - confessed she can no longer party like she used to because of bad hangovers the next day.

She said: ''When you get older, they get worse. I used to be able to go three nights in a row, but now I die the whole [next] day.''

But wise Una has found a way to overcome the hangover blues, adding: ''I have a good trick - you just keep drinking. Hair of the dog works every time!''

Mollie King, 25, and Vanessa White, 23, joined their fellow 'What About Us' hitmakers on the red carpet at the premiere, while Rochelle Humes, 24, missed the occasion after giving birth to daughter Alaia-Mai on Monday (20.05.13).
