The Saturdays star, who is expecting her first baby with footballer Wayne Bridge, was pictured arriving at KISS FM's radio studios in central London this afternoon (1 July).
Earlier today, Frankie revealed on ITV1's Daybreak that she is due to give birth in October, but there's certainly no let up in her schedule!
As she headed into the KISS studios, Frankie was sipping on a yummy fruit smoothie. She teamed her outfit with a pretty pair of flipflops and a pale pink jacket, and she also toted a brown handbag.
It's been a busy few days for The Saturdays, who are promoting their latest single 'Gentleman'.
Last week, Rochelle Humes returned to the stage for her first performance since giving birth to daughter Alaia-Mai.
