Rochelle, 24, was pictured yesterday (9 October) tucking into a massive juicy burger during her lunch break.
The mum-of-one ordered the yummy looking treat while visiting a diner-style restaurant with her Sats bandmates - Una Healy, Mollie King and Vanessa White.
Sharing the snap on Instagram, Rochelle joked: "Just a light lunch..."
The girl group, minus Frankie Sandford who is currently on maternity leave, spent yesterday promoting their new album Living For The Weekend.
Following their pit stop for lunch, Rochelle and the girls headed to their album launch party - where they bizarrely hung out with reggae star Shaggy!
