The former Pussycat Doll, 32, performed at the annual gay rights festival to a packed crowd of fans on Saturday night (23 August) and her growing belly didn't stop her from bouncing around the stage.
Dressed in a gorgeous orange mini-dress with cream belt above her bump, singer and dancer Kimberly looked like she was having a whale of a time.
The Got To Dance judge gave fans a treat when she performed Pussycat Doll hits 'When I Grow Up' and 'Don't Cha'.
Kimberly announced she was expecting her first baby earlier this month.
She is expecting a daughter with her husband Max Rogers and has told fans that she is looking forward to being a mother.
Taking to Twitter on 18 August, the US-born star gushed: "I'm so excited to be a Mum! ....or Mum. Hehe!"
In February, Kimberly married long-term partner Max in a private ceremony and announced the news by simply tweeting: "Just married.. And it was mint."
The couple got engaged last September, following a two-year romance, and guests at their wedding included Kimberly's BFF and former Pussycat Doll bandmate Ashley Roberts and Sinitta, who she starred alongside in C4's The Jump.
