This weekend, the gorgeous pair have been getting in the Christmas spirit and spending lots of girlie time together.
And while getting plenty of attention from her superstar mum is great fun for two-year-old Aoife, we think she might have been a BIT more excited to meet a certain bearded gentleman in red!
Una took her cute daughter to meet Father Christmas at Legoland in Windsor and while we're not sure he was the REAL Santa (who surely must be busy reading letters?), he certainly looked the part!
Posting a few snaps of their fun Saturday (29 November), Una wrote: "Thank you @legolandwindsor for such a fun day x."
Obviously feeling festive, the next day the pair decided to watch a traditional Christmas film.
With Aoife in a red coat perfect for the season, they headed to the premiere of new film Get Santa.
Una tweeted: "Having mother/daughter morning, heading to see the #GetSanta film premiere! Looking forward to hearing @thesaturdays #christmaswrapping."
She later added: "#GetSanta great Christmas movie for all the family x."
The Saturdays recorded a special version of 'Christmas Wrapping' for the upcoming crimbo-comedy, which is due to be released on 5 December.
Una, 32, announced her second pregnancy in September, just a day after The Saturdays kicked off their nationwide 'Greatest Hits Tour'.
She revealed in November that she and husband Ben Foden are expecting a boy.
