As Mel B kick-started the first day of her new job she matched her outfit with her pooch Cookie.

The 44-year-old singer, who replaced TV host Paddy McGuinness as team captain opposite Holly Willoughby, made her Celebrity juice captaincy debut.

Mel split from her husband Stephen Belafonte back in 2017.
