The Saturdays star is now a team captain on the fun BBC3 show, which kicks off again next week, and opted for a bright spring outfit on set.
Rochelle teamed a yellow sleeveless top with black, white and yellow hareem pants and topped off her look with black pointed courts and a low ponytail.
In a collage of snaps posted to Twitter, Rochelle can be seen posing in her dressing room while also getting her make-up done. Stunning!
Sweat The Small Stuff premiered in April last year and mum-of-one Rochelle, who is married to JLS star Marvin Humes, made her debut as Melvin O'Doom's supporting teammate.
She did such a good job, however, that Rochelle will make hr debut as a team captain when the second series launches on Tuesday (7 April).
Earlier this week, Rochelle spoke to Reveal about Sweat The Small Stuff, saying that filming the show actually felt like a "night off".
She said: "It's like a night off, we have so much fun. We get in the best comedians and we really do just have a laugh."
