The Saturdays singer, 24, is expecting her first child with her footballer fiance Wayne Bridge in October and it's fair to say she looks blooming marvellous.
Frankie was pictured today (13 August) arriving at Radio 1's London studios wearing an eye-catching stretchy maxi dress, which she teamed with sparkly black flip-flops.
The mum-to-be kept off the chill with a smart black jacket with gold zip detail and was toting a designer leather handbag on the crook of her arm.
Frankie was chatting on the radio about Time To Change, a campaign by mental health charity Mind.
The star, who has spoken about her battle with depression in the past, is an ambassador for the charity and is backing the initiative, which encourages people to talk about mental health issues.
Last week, Frankie revealed that she would not be performing with her Saturdays bandmates until after her baby son is born.
Frankie is going on her doctor's orders, so will not be appearing at this weekend's V Festival alongside Rochelle Humes, Mollie King, Una Healy and Vanessa White.
Put your feet up, Frankie!
