The Saturdays star has remained out of the public eye since March, with her last performance before maternity leave being a concert at G-A-Y in London.
But today the 24-year-old announced her maternity leave was officially over and she couldn't wait to get stuck back into her day job.
Rochelle tweeted: "First day back at work! Off to a photoshoot. You can be glamorous sporting baby sick on your shirt right? Xx."
We reckon Rochelle could pull that off!
The 'What About Us' singer got a tweet of support from JLS star husband Marvin Humes, who said: "First day back at work for my SuperWoman Wife @RochelleTheSats proud of you..have a good day.. #WomanOfSteel."
Rochelle joked back: "Haha pleased you didn't say Man Of Steel!"
The pop star couple became first-time parents to gorgeous baby daughter Alaia-Mai on 20 May, and treated fans to an adorable family picture last week.
