The former Strictly Come Dancing star and her actor hubby posed with little Betsy at the Tickety Toc launch at the famous London department store on Sunday afternoon (21 July).
Denise looked lovely in a patterned dress and silver sandals – perfect for yesterday's hot temperatures. She kept her hair and make-up minimal for a natural glow.
The 38-year-old recently said Betsy, 3, meant everything to her.
"Every night at 6pm just before her tea-bath-bed routine, we have a dance-off," she told The Telegraph. "We turn up Girls Aloud or something else poppy and just go crazy. It's honestly the highlight of my day."
Other stars at the Hamleys event included The Apprentice runner-up Luisa Zissman, who brought her daughter Dixie.
