Performing on the US chat show with bandmates Frankie Sandford, Mollie King, Una Healy and Vanessa White, Rochelle showed off her latest printed pick of the high-street.
With her hair styled into tumbling curls, the pregnant star didn't let her baby bump stop her perfecting the band's flirty dance routine either. Impressive!
The floral border frock (which is currently sold out online) followed the new season cutout style she wore on the cover of this week's Fabulous magazine.
