The 16-month-old claps her hands and spins in delight, while watching her mum perform at the NIA in Birmingham yesterday (September 15).
Rochelle, 25, posted the clip on Instagram along with the caption: "Our number one fan, Alaia loved watching her Mummy and Aunties tonight! First time I've let her stay up past her bedtime #socute #babyontour #greatesthitslivebirmingham"
Alaia's dad, Marvin Humes, 29, is currently in Las Vegas, as he was DJing at One Direction star Niall Horan's 21st birthday party last night.
After watching the video of his dancing toddler he tweeted to say that he was a 'Proud Daddy'.

Alaia had her first unaccompanied morning at nursery last Friday (September 12) and Rochelle tweeted that she was suffering from a bad case of separation anxiety:
1st day of dropping Alaia to nursery and not staying. Kids were fine, Mums not so much. Just got in the car and cried like a baby. 😥😥🙈

She then added 'I wouldn't mind she's only there till 12.30'
This isn't the first time Rochelle has got 'teary' since becoming a mum. She revealed in a recent interview with Cosmopolitan that she has become more emotional since Alaia was born:
"For the first few months, you're so tired you just want to go to bed. I was so emotional," she said.
"One day, Marvin asked me what I wanted for breakfast and even that set me off. I just wailed 'cereal' across the house. We still joke about it now."
