Frankie, 25, has also been swooning over Jennifer Lopez and Ariana Grande's music videos, before deciding she needs to hit the gym.
Taking to Twitter, mum-of-one Frankie joked: "Just watched Cheryl. Nicole Scherzinger. JLo and Ariana Grande. If you need me. I'll be in the gym..... #thosebodies."
Don't be silly, Frankie, you're looking pretty good considering you gave birth less than a year ago!
Frankie was spotted with her Saturdays bandmates - Rochelle Humes, Una Foden (née Healy), Mollie King and Vanessa White - earlier today (26 June) following a radio interview with Capital FM.
The girls were in London to promote their new single 'What Are You Waiting For?', which is released on 10 August, their forthcoming album Finest Selection: The Greatest Hits and their tour. Phew!
Frankie was dressed in skinny jeans, a white blouse and a casual light denim shirt, and she completed her outfit with a black hat.
The star gave birth to her first child, Parker Bridge, in October 2013 and has gradually lost her baby weight with sensible eating and exercise.
Last month, Frankie showed off the results of her hard work by slipping into a bikini for her hen do in Ibiza.
The singer got engaged to footballer Wayne Bridge last year and they are due to tie-the-knot this summer.
What a busy year it's turning out to be for her!
