Denise brought Betsy along to the Barbie Mariposa & the Fairy Princess DVD & Blu-ray launch event at ZSL London Zoo on Sunday (18 August).
The 39-year-old was wearing a red leopard print dress with black strappy sandals, which she teamed with a slick of red lipstick.
Meanwhile, Betsy was equally colourful in a printed frilly dress and detachable sparkly fairy wings.
Magic FM radio presenter Denise put on a brave face and smiled for photographers, after confirming last month that she had split from her husband of four years, Lee Mead.
We're pretty sure Betsy got spoilt rotten at the event, as she got to pose alongside a real-life Barbie model and explore her creative skills in a craft-making session.
Betsy may only be three years old but it looks like she could be hot on her mummy's heels after she appeared as a guest on Denise's radio show!
Denise invited Betsy, along with Myleene Klass, as guests on her weekend Saturday (17 August) show and posted a photo to Twitter of Betsy sitting in the presenter's chair!
It looked like Betsy was a natural, as she even gave a thumbs up sign. Commenting on the photo, Denise said: "Little miss Betsy (age 3) loving her time rockin the airwaves on @magicfm #proudmummy."
