The Saturdays Rochelle Humes has taken to Twitter to tell fans that those with tickets to the Capital Summertime Ball are in for a treat.

The singer tweeted to her followers: "Just been to take Alaia-Mai to see her Aunties ♥ @TheSaturdays xx"

Rochelle added: "We popped into the rehearsals for @CapitalOfficial summer time ball. If you're going you're in for a treat.. @TheSaturdays Go girls xx"

The 'Gentleman' singer, who will not be performing at the Summertime Ball, also tweeted that she could not wait to be back performing with the group again.
