First-time mum Rochelle, who welcomed Alaia-Mai in May with husband Marvin Humes, headed to the festival over the weekend with her band mates who were scheduled to perform.
Rochelle, who was enjoying the exclusive Virgin Media Louder Lounge on Saturday night (17 August), told Reveal at the Mahiki Coconut Backstage Bar: "It's the first time I've left her overnight and I feel sick, so I'm having a drink.
"My mum's looking after her but I'm still constantly checking and asking 'send me a picture, send me a picture'."
Rochelle, who returned to work in June following her maternity leave, added: "That baby is just everything in my life, I want to go home really."
The doting mum even showed us some cute baby pictures of adorable Alaia-Mai!
Rochelle first performed with her bandmates at the Staffordshire venue on Saturday.
She then headed down to Chelmsford, Essex to watch Beyoncé headline, and spent time afterwards partying with band mates Una Healy, Mollie King and Vanessa White, as well as Tulisa and Alexandra Burke.
Rochelle also expressed her feelings on Twitter. She said: "I love my little family so much. @MarvinHumes and our Alaia-Mai. The best things in the whole world. My whole world. *stops drinking wine*."
The 'What About Us' singer wasn't away from Alaia-May for long though, and on Monday took the little tot to work as she made a radio appearance at the BBC Radio 1 studios.
